Tensor Products of Multimatroids and a Brylawski-Type Formula for the Transition Polynomial

Abstract Brylawski’s tensor product formula expresses the Tutte polynomial of the tensor product of two graphs or matroids in terms of Tutte polynomials arising from the tensor factors. Analogous tensor product formulas are known for the Bollobás–Riordan and transition polynomial...
