A combinatorial description of the Heegaard Floer contact invariant

Olga Plamenevskaya

Algebraic & Geometric Topology 7 (2007) 1201–1209

arXiv: math.GT/0612322

Abstract

We observe that the Heegaard Floer contact invariant is combinatorial by applying the algorithm of Sarkar–Wang to the description of the contact invariant due to Honda–Kazez–Matić. We include an example of this combinatorial calculation.
