A surgery triangle for lattice cohomology

Joshua Evan Greene

Algebraic & Geometric Topology 13 (2013) 441–451
Abstract

Lattice cohomology, defined by Némethi in [Publ. Res. Inst. Math. Sci. 44 (2008) 507–543], is an invariant of negative definite plumbed 3–manifolds which conjecturally computes their Heegaard Floer homology HF+. We prove a surgery exact triangle for the lattice cohomology analogous to the one for HF+. This is a step towards relating these two invariants.

Keywords
Heegaard Floer homology, lattice cohomology, plumbed manifold
