Independence complexes of circle graphs

Geometric Topology 2024-12-03 v1

Abstract

Independence complexes of circle graphs are purely combinatorial objects. However, when constructed from some diagram of a link LL, they reveal topological properties of LL, more specifically, of its Khovanov homology. We analyze the homotopy type of independence complexes of circle graphs, with a focus on those arising when the graph is bipartite. Moreover, we compute (real) extreme Khovanov homology of a 44-strand pretzel knot using chord diagrams and independence complexes.
