Fukaya categories of plumbings and multiplicative preprojective algebras
2019
Quantum Topology
Given an arbitrary graph Γ and non-negative integers g v for each vertex v of Γ, let X Γ be the Weinstein 4-manifold obtained by plumbing copies of T * Σ v according to this graph, where Σ v is a surface of genus g v . We compute the wrapped Fukaya category of X Γ (with bulk parameters) using Legendrian surgery extending our previous work [14] where it was assumed that g v = 0 for all v and Γ was a tree. The resulting algebra is recognized as the (derived) multiplicative preprojective algebra
