Exact Lagrangians in the cotangent bundle of a sphere and a torus

Symplectic Geometry 2022-11-30 v1

Abstract

It is known that any closed, exact Lagrangian in the cotangent bundle of a closed, smooth manifold is of the same homotopy type as the zero section. In this paper, we give a Fukaya-theoretic proof of this fact for the sphere and torus to review and demonstrate some of the homological algebra techniques in symplectic geometry.
