Weight systems and invariants of graphs and embedded graphs
Maxim Kazaryan, Sergei Lando
We describe recent achievements in the theory of weight systems, which are functions on chord diagrams satisfying so-called -term relations. Our main attention is devoted to con…

Skew characteristic polynomial of graphs and embedded graphs
R. Dogra, S. Lando
We introduce a new one-variable polynomial invariant of graphs, which we call the skew characteristic polynomial. For an oriented simple graph, this is just the characteristic poly…

Polynomial graph invariants and the KP hierarchy
Sergei Chmutov, Maxim Kazarian, Sergey Lando
We prove that the generating function for the symmetric chromatic polynomial of all connected graphs satisfies (after appropriate scaling change of variables) the Kadomtsev--Petvia…
