The multivariate arithmetic Tutte polynomial [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
We introduce an arithmetic version of the multivariate Tutte polynomial recently studied by Sokal, and a quasi-polynomial that interpolates between the two.

Computing Tutte Polynomials [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
We present a new edge selection heuristic and vertex ordering heuristic that together enable one to compute the Tutte polynomial of much larger sparse graphs than was previously doable.

Modifications of Tutte–Grothendieck invariants and Tutte polynomials [PDF]

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
Generalized Tutte–Grothendieck invariants are mappings from the class of matroids to a commutative ring that are characterized recursively by contraction–deletion rules. Well known examples are Tutte, chromatic, tension and flow polynomials.

Simulating quantum computations with Tutte polynomials [PDF]

open access: yesnpj Quantum Information, 2021
We establish a classical heuristic algorithm for exactly computing quantum probability amplitudes. Our algorithm is based on mapping output probability amplitudes of quantum circuits to evaluations of the Tutte polynomial of graphic matroids.

A Tutte polynomial for toric arrangements [PDF]

open access: yesTransactions of the American Mathematical Society, 2010
We introduce a multiplicity Tutte polynomial M(x,y), with applications to zonotopes and toric arrangements. We prove that M(x,y) satisfies a deletion-restriction recurrence and has positive coefficients.

Dirac traces and the Tutte polynomial

open access: yesJournal of High Energy Physics
Perturbative calculations involving fermion loops in quantum field theories require tracing over Dirac matrices. A simple way to regulate the divergences that generically appear in these calculations is dimensional regularisation, which has the ...

A lattice point counting generalisation of the Tutte polynomial [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
The Tutte polynomial for matroids is not directly applicable to polymatroids. For instance, deletion- contraction properties do not hold. We construct a polynomial for polymatroids which behaves similarly to the Tutte polynomial of a matroid, and in fact

Fourientation activities and the Tutte polynomial [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
A fourientation of a graph G is a choice for each edge of the graph whether to orient that edge in either direction, leave it unoriented, or biorient it.

The arithmetic Tutte polynomials of the classical root systems [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
Many combinatorial and topological invariants of a hyperplane arrangement can be computed in terms of its Tutte polynomial. Similarly, many invariants of a hypertoric arrangement can be computed in terms of its arithmetic Tutte polynomial. We compute the

On the evaluation of the Tutte polynomial at the points (1,-1) and (2,-1) [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2011
C. Merino [Electron. J. Combin. 15 (2008)] showed that the Tutte polynomial of a complete graph satisfies $t(K_{n+2};2,-1)=t(K_n;1,-1)$. We first give a bijective proof of this identity based on the relationship between the Tutte polynomial and the ...
