Abstract In this thesis we give an introduction to Seiberg-Witten gauge theory used to study compact oriented four-dimensional manifolds X. Seiberg-Witten theory uses a Spin c structure to create two vector bundles over X called the spinor bundle and determinant line bundle. One then considers the set of solutions to the Seiberg-Witten equations, which are expressed in terms of a section of the spinor bundle and a Dirac operator formed out of a connection on the determinant line bundle. After taking the quotient by an action of a U(1)-gauge group, one constructs an invariant by integrating cohomology classes over the resulting moduli space. In this thesis we show these Seiberg-Witten invariants can be used to find obstructions to the existence of a symplectic structure on X.

…Hence any self-adjoint Fredholm operator has index 0. An important fact of Fredholm operators is that their index is invariant under perturbations. In other words, if one were to take a family of Fredholm operators parameterized by some connected…

…topological space, all of their indices would agree. There is a broad theory on determining Fredholmness of operators and calculating their index. A key concept is that of ellipticity. Let π : T ∗ X → X be the natural projection. Let E and F be vector bundles…

…without going to a local description of D. One of the main reasons for introducing the notion of ellipticity is that most differential operators encountered in geometry satisfy this condition, but moreover that we have the following result. Theorem 2.4.5…
