Thistlethwaite Theorems for Knotoids and Linkoids

Sergei Chmutov, Qingying Deng, Joanna A. Ellis-Monaghan +2

The classical Thistlethwaite theorem for links can be phrased as asserting that the Kauffman bracket of a link can be obtained from an evaluation of the Bollobás-Riordan polynomial…

Partial duality for ribbon graphs

Sergei Chmutov

This is an expository paper extending the tutorial talk at the MATRIX Workshop on Uniqueness and Discernment in Graph Polynomials in October 2023. The explanation is mainly based o…

Partial-dual genus polynomial as a weight system

Sergei Chmutov

We prove that the partial-dual genus polynomial considered as a function on chord diagrams satisfies the four-term relation. Thus it is a weight system from the theory of Vassiliev…

On a conjecture of Gross, Mansour and Tucker

Sergei Chmutov, Fabien Vignes-Tourneret

Partial duality is a duality of ribbon graphs relative to a subset of their edges generalizing the classical Euler-Poincare duality. This operation often changes the genus. Recentl…

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…
