Permutation Tutte polynomial Csongor Beke, Gergely Kál Csáji, Péter Csikvári, Sára Pituk Abstract The classical Tutte polynomial is a two-variate polynomial 𝑇𝐺(𝑥,𝑦) associated to graphs or more generally, matroids. In this paper, we introduce a polynomial 𝑇˜𝐻(𝑥,𝑦) associated to a bipartite graph 𝐻 that we call the permutation Tutte polynomial of the graph 𝐻. It turns out that 𝑇𝐺(𝑥,𝑦) and 𝑇˜𝐻(𝑥,𝑦) share many properties, and the […]
