The Lagrangian cobordism group of $T^2$

Symplectic Geometry 2015-07-21 v3

Abstract

We compute the Lagrangian cobordism group of the standard symplectic 2-torus and prove that it is isomorphic to the Grothendieck group of its derived Fukaya category. The proofs use homological mirror symmetry for the 2-torus.
