The twisted Floer homology of torus bundles

Yinghua Ai and Thomas D Peters

Algebraic & Geometric Topology 10 (2010) 679–695

DOI: 10.2140/agt.2010.10.679
Abstract

We prove an exact sequence for ω–twisted Heegaard Floer homology. As a corollary, given a torus bundle Y over the circle and a cohomology class [ω] in H2(Y ; Z) which evaluates nontrivially on the fiber, we compute the Heegaard Floer homology of Y with twisted coefficients in the universal Novikov ring.
