Chromatic roots are dense in the whole complex plane [PDF]
, 2004 I show that the zeros of the chromatic polynomials P-G(q) for the generalized theta graphs Theta((s.p)) are taken together, dense in the whole complex plane with the possible exception of the disc \q - l\ < l.

Structure of the flow and Yamada polynomials of cubic graphs
, 2018 We establish a quadratic identity for the Yamada polynomial of ribbon cubic graphs in 3-space, extending the Tutte golden identity for planar cubic graphs. An application is given to the structure of the flow polynomial of cubic graphs at zero.

Splitting Formulas for Tutte Polynomials
Journal of Combinatorial Theory, Series B, 1997 The Tutte polynomial is a central invariant of a matroid. In particular, many numerical invariants of a matroid can be calculated by evaluating or calculating coefficients of the Tutte polynomial. Moreover, for certain cases there is a close connection between the Tutte polynomial and the Jones and Kauffman polynomial of a link.

Torus orbits on homogeneous varieties and Kac polynomials of quivers
, 2013 In this paper we prove that the counting polynomials of certain torus orbits in products of partial flag varieties coincides with the Kac polynomials of supernova quivers, which arise in the study of the moduli spaces of certain irregular meromorphic ...

Computing the Tutte Polynomial of a Matroid from its Lattice of Cyclic Flats [PDF]
, 2014 We show how the Tutte polynomial of a matroid $M$ can be computed from its condensed configuration, which is a statistic of its lattice of cyclic flats.

The Tutte Polynomial of a Morphism of Matroids 5. Derivatives as Generating Functions of Tutte Activities [PDF]
, 2012 We show that in an ordered matroid the partial derivative \partial^{p+q}t/\partialx^p\partialyq of the Tutte polynomial is p!q! times the generating function of activities of subsets with corank p and nullity q.
