Second extra differential on odd graph complexes
Marko Živković
A suitable extra differential on graph complexes can lead to a pairing of its cohomological classes. Many such extra differentials are known for various graph complexes, including…
Hairy graphs to ribbon graphs via a fixed source graph complex
Assar Andersson, Marko Živković
We show that the hairy graph complex appears as an associated graded complex of the oriented graph complex , subject to the filtration on the number…
Multi-directed graph complexes and quasi-isomorphisms between them I: oriented graphs
Marko Živković
We construct a direct quasi-isomorphism from Kontsevich's graph complex GC_n to the oriented graph complex OGC_{n+1}, thus providing an alternative proof that the two complexes are…
Differentials on Graph Complexes III - Deleting a Vertex
Marko Živković
We prove that the hairy graph complex with the extra differential is almost acyclic. This justifies the construction of hairy graph cohomology classes by the waterfall mechanism. T…
