Dynamic inter-electronic correlations are exquisitely local effects responsible for many interesting phenomena in molecular physics, including much or all of mutual attractions between molecules. The main thrust of this work is the development of high-accuracy, low-scaling models of electron correlation exploiting locality in the context of non-covalent interactions.

▼ The voter model which describes the flow of information through interactions between neighbors has been widely studied in the field of probability. In this paper we study two variations of the voter model, one is called the Latent Voter Model and the other is called the Zealot Voter Model. Both models are implemented in a space that is a random graph. In the latent voter model, which models the spread of a technology through a social network, individuals who have just changed their choice have a latent period, which is exponential with rate λ, during which they will not buy a new device. We study site and edge versions of this model on random graphs generated by a configuration model in which the degrees d(x) have 3 ≤ d(x) ≤ M. We show that if the number of vertices n → ∞ and log n \ll λ_n \ll n then the fraction of 1's at time λ_n t converges to the solution of du/dt = c_pu(1-u)(1-2u). Using this we show the latent voter model has a quasi-stationary state in which each opinion has probability \approx 1/2 and persists in this state for a time that is ≥ n^m for any m<∞. Thus, even a very small latent period drastically changes the behavior of the voter model, which has a one parameter family of stationary distributions and reaches fixation in time O(n). Inspired by the spread of discontent as in the 2016 presidential election, we consider a voter model in which 0's are ordinary voters and 1's are zealots. Thinking of a social network, but desiring the simplicity of an infinite object that can have a nontrivial stationary distribution, space is represented by a tree. The dynamics are a variant of the biased voter: if x has degree d(x) then at rate d(x)p_k the individual at x consults k ≥ 1 neighbors. If at least one neighbor is 1, they adopt state 1, otherwise they become 0. In addition at rate p₀ individuals with opinion 1 change to 0. As in the contact process on trees, we are interested in determining when the zealots survive and when they will survive locally, i.e., the root of the tree is in state 1 infinitely often. Advisors/Committee Members: Durrett, Rick T (advisor).

Subjects/Keywords: Mathematics; branching random walk; coalescing random walk; configuration model; global survival and local survival; the voter model; voter model perturbation

Este trabalho tem como proposta apresentar a metodologia de diagnóstico de influência local de Cook (1986) conjuntamente com a metodologia de seleção da perturbação adequada proposta por Zhu et al. (2007) no modelo de calibração ultraestrutural com réplicas. A metodologia de Cook (1986) ser´a utilizada para investigar a robustez e a sensibilidade do modelo, onde os esquemas de perturbação adotados foram ponderação de casos e na variável resposta. Perturbar o modelo e/ou os dados de forma arbitrária pode conduzir a interpretações sobre a análise de diagnóstico e a conclusões equivocadas. Portanto, este trabalho irá avaliar as perturbações propostas segundo a metodologia de Zhu et al. (2007) e caso as perturbações não sejam adequadas, iremos propor uma nova forma de fazer as perturbações. Foi utilizado como aplicação a análise de um conjunto de dados com réplicas balanceadas e foram avaliadas quais patamares e laboratórios exercem um efeito desproporcional nas inferências feitas sob o modelo.

This paper aims to present the local influence diagnostic methodology of Cook (1986) along with the selection of the appropriate perturbation schemes proposed by Zhu et al. (2007) in ultrastructural calibration model with replicas. The methodology of Cook (1986) will be used to investigate the robustness and sensitivity of model, where the adopted perturbation schemes were weighting cases and response variables. Perturbing the model and/or data in an arbitrary way can lead to miss interpretations of diagnostic analysis and wrong conclusions. Therefore, this study will evaluate the induced perturbations according to the methodology of Zhu et al. (2007) and if the perturbations are not suitable, we will propose a new way of perturbing the model or the data. As an application it was considered a data set with balanced repeated replication to evaluate which levels and laboratories exercise a disproportional effect on inferences made in the model.

Dans cette thèse, nous étudions l’existence, non existence et multiplicité des ondes stationnairesavec les normes prescrites pour deux types d’équations aux dérivées partiellesnon linéaires elliptiques découlant de différents modèles physiques. La stabilité orbitale desondes stationnaires est également étudiée dans certains cas. Les principales méthodes denos preuves sont des arguments variationnels. Les solutions sont obtenues comme pointscritiques de fonctionnelle associée sur une contrainte.La thèse se compose de sept chapitres. Le Chapitre 1 est l’introduction de la thèse. Dansles Chapitres 2 à 4, nous étudions une classe d’équations de Schrödinger-Poisson-Slaternon linéaires. Nous établissons dans le Chapitre 2 des résultats optimaux non existencede solutions d’énergie minimale ayant une norme L2 prescrite. Dans le Chapitre 3, nousmontrons un résultat d’existence de solutions L2 normalisées, dans une cas où la fonctionnelleassociée n’est pas bornée inférieurement sur la contrainte. Nos solutions sonttrouvées comme des points de selle de la fonctionnelle, mais ils correspondent à des solutionsd’énergée minimale. Nous montrons également que les ondes stationnaires associéessont orbitalement instables. Ici, puisque nos points critiques présumés ne sont pas desminimiseurs globaux, il n’est pas possible d’utiliser de façon systématique les méthodesde compacité par concentration développées par P. L. Lions. Ensuite, dans le Chapitre4, nous montrons que sous les hypothèses du Chapitre 3, il existe une infinité de solutionsayant une norme L2 prescrite. Dans les deux chapitres suivants, nous étudions uneclasse d’équations de Schrödinger quasi-linéaires. Des résultats optimaux non existence desolutions d’énergie minimale sont donnés dans le Chapitre 5. Dans le Chapitre 6, nousprouvons l’existence de deux solutions positives ayant une norme donnée. L’une d’elles,relativement à la contrainte L2, est de type point selle. L’autre est un minimum, soit localou global. Le fait que la fonctionnelle naturelle associée à cette équation n’est pas biendéfinie nécessite l’utilisation d’une méthode de perturbation pour obtenir ces deux pointscritiques. Enfin, au Chapitre 7, nous mentionnons quelques questions que cette thèse asoulevées.

In this thesis, we study the existence, non-existence and multiplicity of standing waves withprescribed norms for two types of nonlinear elliptic partial differential equations arisingfrom various physical models. The orbital stability of the standing waves is also discussedin some cases. The main ingredients of our proofs are variational arguments. The solutionsare found as critical points of an associated functional on a constraint.The thesis consists of seven chapters. Chapter 1 is the Introduction of the thesis.In Chapters 2 to 4, we study a class of nonlinear Schrödinger-Poisson-Slater equations.We establish in Chapter 2 sharp non-existence results of least energy solutions having aprescribed L2-norm. In Chapter 3 we prove an existence result for L2-normalized solutions,in a situation where the…

▼ L'objet de cette thèse est d'étudier le comportement en temps long de solutions d'équations d'évolution non locales ainsi que la limite singulière d'équations et de systèmes d'équations aux dérivées partielles, où intervient un petit paramètre epsilon. Au Chapitre 1, nous considérons une équation de réaction-diffusion non locale avec conservation au cours du temps de l'intégrale en espace de la solution; cette équation a été initialement proposée par Rubinstein et Sternberg pour modéliser la séparation de phase dans un mélange binaire. Le problème de Neumann associé possède une fonctionnelle de Lyapunov, c'est-à-dire une fonctionnelle qui décroit selon les orbites. Après avoir prouvé que la solution est confinée dans une région invariante, nous étudions son comportement en temps long. Nous nous appuyons sur une inégalité de Lojasiewicz pour montrer qu'elle converge vers une solution stationnaire quand t tend vers l'infini. Nous évaluons également le taux de la convergence et calculons précisément la solution stationnaire limite en dimension un d'espace. Le Chapitre 2 est consacré à l'étude de l'équation différentielle non locale que l'on obtient en négligeant le terme de diffusion dans l'équation d'Allen-Cahn non locale étudiée au Chapitre 1. Sans le terme de diffusion, la solution ne peut pas être plus régulière que la fonction initiale. C'est la raison pour laquelle on ne peut pas appliquer la méthode du Chapitre 1 pour l'étude du comportement en temps long de la solution. Nous présentons une nouvelle méthode basée sur la théorie des réarrangements et sur l'étude du profil de la solution. Nous montrons que la solution est stable pour les temps grands et présentons une caractérisation détaillée de sa limite asymptotique quand t tend vers l'infini. Plus précisément, la fonction limite est une fonction en escalier, qui prend au plus deux valeurs, qui coïncident avec les points stables d'une équation différentielle associée. Nous montrons aussi par un contre-exemple non trivial que, quand une hypothèse sur la fonction initiale n'est pas satisfaite, la fonction limite peut prendre trois valeurs, qui correspondent aux points instable et stables de l'équation différentielle associée. Nous étudions au Chapitre 3 une équation différentielle ordinaire non locale qui a éte proposée par M. Nagayama. Une difficulté essentielle est que le dénominateur dans le terme de réaction non local peut s'annuler. Nous appliquons un théorème de point fixe lié a une application contractante pour démontrer que le problème à valeur initiale correspondant possède une solution unique qui reste connée dans un ensemble invariant. Ce problème possède une fonctionnelle de Lyapunov, qui est un ingrédient essentiel pour démontrer que la solution converge vers une solution stationnaire constante par morceaux quand t tend vers l'infini. Au Chapitre 4, nous considérons un modèle d'interface diffuse pour la croissance de tumeurs, où intervient une équation d'ordre quatre de type Cahn Hilliard. Après avoir introduit un modèle de champ de phase associé, on… Advisors/Committee Members: Hilhorst, Danielle (thesis director).
