▼ In Chapter One the theoretical basis for infinitesimal transformations is presented with particular emphasis on the central theme of this thesis which is the invariance of ordinary differential equations, and their first integrals, under infinitesimal transformations. The differential operators associated with these infinitesimal transformations constitute an algebra under the operation of taking the Lie Bracket. Some of the major results of Lie's work are recalled. The way to use the generators of symmetries to reduce the order of a differential equation and/or to find its first integrals is explained. The chapter concludes with a summary of the state of the art in the mid-seventies just before the work described here was initiated. Chapter Two describes the growing awareness of the algebraic properties of the paradigms of differential equations. This essentially ad hoc period demonstrated that there was value in studying the Lie method of extended groups for finding first integrals and so solutions of equations and systems of equations. This value was emphasised by the application of the method to a class of nonautonomous anharmonic equations which did not belong to the then pantheon of paradigms. The generalised Emden-Fowler equation provided a route to major development in the area of the theory of the conditions for the linearisation of second order equations. This was in addition to its own interest. The stage was now set to establish broad theoretical results and retreat from the particularism of the seventies. Chapters Three and Four deal with the linearisation theorems for second order equations and the classification of intrinsically nonlinear equations according to their algebras. The rather meagre results for systems of second order equations are recorded. In the fifth chapter the investigation is extended to higher order equations for which there are some major departures away from the pattern established at the second order level and reinforced by the central role played by these equations in a world still dominated by Newton. The classification of third order equations by their algebras is presented, but it must be admitted that the story of higher order equations is still very much incomplete. In the sixth chapter the relationships between first integrals and their algebras is explored for both first order integrals and those of higher orders. Again the peculiar position of second order equations is revealed. In the seventh chapter the generalised Emden-Fowler equation is given a more modern and complete treatment. The final chapter looks at one of the fundamental algebras associated with ordinary differential equations, the three element 8£(2, R), which is found in all higher order equations of maximal symmetry, is a fundamental feature of the Pinney equation which has played so prominent a role in the study of nonautonomous Hamiltonian systems in Physics and is the signature of Ermakov systems and their generalisations.

Die vorliegende Arbeit widmet sich der Spektraltheorie von Differentialoperatoren auf metrischen Graphen und von indefiniten Differentialoperatoren auf beschränkten Gebieten. Sie besteht aus zwei Teilen. Im Ersten werden endliche, nicht notwendigerweise kompakte, metrische Graphen und die Hilberträume von quadratintegrierbaren Funktionen auf diesen betrachtet. Alle quasi-m-akkretiven Laplaceoperatoren auf solchen Graphen werden charakterisiert, und Abschätzungen an die negativen Eigenwerte selbstadjungierter Laplaceoperatoren werden hergeleitet. Weiterhin wird die Wohlgestelltheit eines gemischten Diffusions- und Transportproblems auf kompakten Graphen durch die Anwendung von Halbgruppenmethoden untersucht. Eine Verallgemeinerung des indefiniten Operators -tfrac{d}{dx}sgn(x)tfrac{d}{dx} von Intervallen auf metrische Graphen wird eingeführt. Die Spektral- und Streutheorie der selbstadjungierten Realisierungen wird detailliert besprochen. Im zweiten Teil der Arbeit werden Operatoren untersucht, die mit indefiniten Formen der Art langlegrad v, A(cdot)grad urangle mit u,vin H₀¹(Omega)subset L²(Omega) und ΩsubsetR^d beschränkt, assoziiert sind. Das Eigenwertverhalten entspricht in Dimension d=1 einer verallgemeinerten Weylschen Asymptotik und für dgeq 2 werden Abschätzungen an die Eigenwerte bewiesen. Die Frage, wann indefinite Formmethoden für Dimensionen dgeq 2 anwendbar sind, bleibt offen und wird diskutiert.

This thesis is devoted to the spectral theory of differential operators on metric graphs and of indefinite differential operators on bounded domains. It consists of two parts. In the first part finite not necessarily compact metric graphs and the Hilbert spaces of square integrable functions on these graphs are considered. All quasi-m-accretive Laplacians on such graphs are characterized and estimates on the negative eigenvalues of self-adjoint Laplacians are derived. Furthermore the well-posedness of a mixed transport and diffusion problem on a compact metric graph is studied in terms of semigroups. The indefinite operator -tfrac{d}{dx}sgn(x)tfrac{d}{dx} is generalized from intervals to finite metric graphs. The spectral and the scattering theory of the self-adjoint realizations are elaborated in detail. In the second part operators are studied that are associated with indefinite quadratic forms of the type langlegrad v, A(cdot)grad urangle, where u,vin H₀¹(Omega)subset L²(Omega) and ΩsubsetR^d bounded. In dimension d=1 the asymptotic distribution of eigenvalues satisfies a generalized Weyl law and for dimension dgeq2 estimates on the eigenvalues are derived. The problem when indefinite form methods apply in dimensions dgeq 2 constitutes an open problem and is discussed as well.

▼ In this dissertation we study non-negative self-adjoint Laplace type operators acting on smooth sections of a vector bundle. First, we assume base manifolds are compact, boundaryless, and Riemannian. We start from the Fourier integral operator representation of half-wave operators, continue with spectral zeta functions, heat and resolvent trace asymptotic expansions, and end with the quantitative Wodzicki residue method. In particular, all of the asymptotic coefficients of the microlocalized spectral counting function can be explicitly given and clearly interpreted. With the auxiliary pseudo-differential operators ranging all smooth endomorphisms of the given bundle, we obtain certain asymptotic estimates about the integral kernel of heat operators. As applications, we study spectral asymptotics of Dirac type operators such as characterizing those for which the second coefficient vanishes. Next, we assume vector bundles are trivial and base manifolds are Euclidean domains, and study non-negative self-adjoint extensions of the Laplace operator which acts component-wise on compactly supported smooth functions. Using finite propagation speed estimates for wave equations and explicit Fourier Tauberian theorems obtained by Yuri Safarov, we establish the principle of not feeling the boundary estimates for the heat kernel of these operators. In particular, the implied constants are independent of self-adjoint extensions. As a by-product, we affirmatively answer a question about upper estimate for the Neumann heat kernel. Finally, we study some specific values of the spectral zeta function of two-dimensional Dirichlet Laplacians such as spectral determinant and Casimir energy. For numerical purposes we substantially improve the short-time Dirichlet heat trace asymptotics for polygons. This could be used to measure the spectral determinant and Casimir energy of polygons whenever the first several hundred or one thousand Dirichlet eigenvalues are known with high precision by other means.

This thesis is devoted to the study of Picard-Fuchs operators associated to one-parameter families of n-dimensional Calabi-Yau manifolds whose solutions are integrals of (n,0)-forms over locally constant n-cycles. Assuming additional conditions on these families, we describe algebraic properties of these operators which leads to the purely algebraic notion of operators of CY-type. rnMoreover, we present an explicit way to construct CY-type operators which have a linearly rigid monodromy tuple. Therefore, we first usernthe translation of the existence algorithm by N. Katz for rigid local systems to the level of tuples of matrices which was established by M. Dettweiler and S. Reiter. An appropriate translation to the level of differential operators yields families which contain operators of CY-type. rnConsidering additional operations, we are also able to construct special CY-type operators of degree four which have a non-linearly rigid monodromy tuple. This provides both previously known and new examples.

In der vorliegenden Arbeit besch"aftige ich mich mit Picard-Fuchs Operatoren f"ur Familien von Calabi-Yau Mannigfaltigkeiten der Dimension n mit einem Deformationsparameter, deren L"osungen durch Integrale einer (n,0)-Form "uber lokal konstante n-Zykel gegeben sind. Ich beschreibe algebraische Eigenschaften dieser Differenzialoperatoren f"ur Familien, die weiteren Bedingungen unterliegen. Dies f"uhrt zum rein algebraischen Begriff des Differenzialoperators vom CY-Typ. F"ur diejenigen, deren Monodromietupel linear starr ist, stelle ich auss erdem eine explizite Konstruktionsmethode vor. Hierzu verwende ich den Existenzalgorithmus f"ur linear starre lokale Systeme von N. Katz und die von M. Dettweiler und S. Reiter erarbeitete Version desselben f"ur Matrixtupel. Daraufhin entwickele ich eine geeignete Version f"ur Differenzialoperatoren, was zu Familien f"uhrt, die Differenzialoperatoren vom CY-Typ enthalten. Des Weiteren bin ich unter Verwendung zus"atzlicher Operationen in der Lage spezielle Differenzialoperatoren vierter Ordnung vom CY-Typ zu konstruieren, deren Monodromietupel nicht linear starr ist. Dies f"uhrt sowohl zu bereits bekannten als auch zu neuen Beispielen f"ur Operatoren dieser Klasse.

Les travaux réalisés dans cette thèse concernent l’étude de problèmes quasi-linéaires paraboliques et elliptiques singuliers. Par singularité, nous signifions que le problème fait intervenir une non linéarité qui explose au bord du domaine où l’équation est posée. La présence du terme singulier entraine un manque de régularité des solutions. Ce défaut de régularité génère en conséquence un manque de compacité qui ne permet pas d’appliquer directement les méthodes classiques d’analyse non linéaires pour démontrer l’existence de solutions et discuter les propriétés de régularité et de comportement asymptotique des solutions. Pour contourner cette difficulté dans le contexte des problèmes que nous avons étudiés, nous sommes amenés à établir des estimations a priori très fines au voisinage du bord en combinant diverses méthodes : méthodes de monotonie (reliées au principe du maximum), méthodes variationnelles, argument de convexité, méthodes d’interpolation dans les espaces de Sobolev, méthodes de point fixe.

In this thesis I have studied the Evolution p-laplacian equation with singular nonlinearity. We start by studying the corresponding elliptic problem and then by defining a proper cone in a suitable Sobolev space find the uniqueness of the solution. Taking that into account and using the semi discretization in time we arrive at the uniqueness and existence result. Next we prove some regularity theorem using tools from Nonlinear Semigroup theory and Interpolation spaces. We also establish some related result for the laplacian case where we improve our result on the existence and regularity, due to the non degeneracy of the laplacian. In another related work we work with a semilinear equation with singular nonlinearity and using the moving plane method prove the symmetry properties of any classical solution. We also give some related apriori estimates which together with the symmetry provide us the existence of solution using the bifurcation result.

Dans cette thèse, nous nous intéressons aux propriétés spectrales des opérateurs non-auto-adjoints aléatoires. Nous allons considérer principalement les cas des petites perturbations aléatoires de deux types des opérateurs non-auto-adjoints suivants :1. une classe d’opérateurs non-auto-adjoints h-différentiels Ph, introduite par M. Hager [32],dans la limite semiclassique (h→0); 2. des grandes matrices de Jordan quand la dimension devient grande (N→∞). Dans le premier cas nous considérons l’opérateur Ph soumis à de petites perturbations aléatoires. De plus, nous imposons que la constante de couplage δ vérifie e (-1/Ch) ≤ δ ⩽ h(k), pour certaines constantes C, k > 0 choisies assez grandes. Soit ∑ l’adhérence de l’image du symbole principal de Ph. De précédents résultats par M. Hager [32], W. Bordeaux-Montrieux [4] et J. Sjöstrand [67] montrent que, pour le même opérateur, si l’on choisit δ ⪢ e(-1/Ch), alors la distribution des valeurs propres est donnée par une loi de Weyl jusqu’à une distance ⪢ (-h ln δ h) 2/3 du bord de ∑. Nous étudions la mesure d’intensité à un et à deux points de la mesure de comptage aléatoire des valeurs propres de l’opérateur perturbé. En outre, nous démontrons des formules h-asymptotiques pour les densités par rapport à la mesure de Lebesgue de ces mesures qui décrivent le comportement d’un seul et de deux points du spectre dans ∑. En étudiant la densité de la mesure d’intensité à un point, nous prouvons qu’il y a une loi de Weyl à l’intérieur du pseudospectre,une zone d’accumulation des valeurs propres dûe à un effet tunnel près du bord du pseudospectre suivi par une zone où la densité décroît rapidement. En étudiant la densité de la mesure d’intensité à deux points, nous prouvons que deux valeurs propres sont répulsives à distance courte et indépendantes à grande distance à l’intérieur de ∑. Dans le deuxième cas, nous considérons des grands blocs de Jordan soumis à des petites perturbations aléatoires gaussiennes. Un résultat de E.B. Davies et M. Hager [16] montre que lorsque la dimension de la matrice devient grande, alors avec probabilité proche de 1, la plupart des valeurs propres sont proches d’un cercle. De plus, ils donnent une majoration logarithmique du nombre de valeurs propres à l’intérieur de ce cercle. Nous étudions la répartition moyenne des valeurs propres à l’intérieur de ce cercle et nous en donnons une description asymptotique précise. En outre, nous démontrons que le terme principal de la densité est donné par la densité par rapport à la mesure de Lebesgue de la forme volume induite par la métrique de Poincaré sur la disque D(0, 1).

In this thesis we are interested in the spectral properties of random non-self-adjoint operators. Weare going to consider primarily the case of small random perturbations of the following two types of operators: 1. a class of non-self-adjoint h-differential operators Ph, introduced by M. Hager [32], in the semiclassical limit (h→0); 2. large Jordan block matrices as the dimension of the matrix gets large (N→∞). In case 1 we are going to…
