Abstract:We construct the Fukaya category of a closed surface equipped with an area form using only elementary (essentially combinatorial) methods. We also compute the Grothendieck group of its derived category.
“…This is not surprising since the map from torus equivariant Kähler classes on P 1 × P 1 has a one dimensional kernel and so there is a non-trivial relation between 1 …”

“…According to definition 2.1 the Fukaya-Seidel category is the A ∞ -category of modules over the A ∞ -version of the path algebra of this quiver where the higher products are given by disk instantons. With additional work, one can check that 1 …”

“…Let (Y ω) be an open symplectic manifold, and let w : Y → C be a symplectic Lefschetz fibration, i.e. a C ∞ complexvalued function with isolated non-degenerate critical points 1 . This means that the smooth parts of the fibers of w are symplectic submanifolds of (Y ω), and that near each we can find a ω-adapted almost complex structure on Y so that in almost-complex local coordinates w is given by w( 1 ) = w( )+ 2 1 +· · ·+ 2 .…”

“…To learn about X by studying the GLSM, it is important to be able to recognize the extra vacua. Let Z be a toric variety defined as a symplectic quotient of C N by a linear action of the gauge group G U (1) . The weights of this action will be denoted Q , where = 1 N and = 1 .…”
Abstract:In this paper we outline the foundations of Homological Mirror Symmetry for manifolds of general type. Both Physics and Categorical prospectives are considered.

We compute the Lagrangian cobordism group of the standard symplectic 2-torus and show that it is isomorphic to the Grothendieck group of its derived Fukaya category. The proofs use homological mirror symmetry for the 2-torus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
