  1. 1. Equivariant Cohomology and Localisation

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Jaume Alonso i Fernández; [2015]
    Keywords : Equivariant Cohomology; localisation;

    Abstract : Equivariant localisation is based on exploiting certain symmetries of some systems, generally represented by a non-free action of a Lie group on a manifold, to reduce the dimensionality of integral calculations that commonly appear in theoretical physics. In this work we present Cartan's model of equivariant cohomology in different scenarios, such as differential manifolds, symplectic manifolds or vector bundles and we reproduce the main corresponding localisation results.
