We generalize and unify results on parametrized and coloured Tutte polynomials of graphs and matroids due to Zaslavsky [Trans. Amer. Math. Soc. 334 (1992), 317-347] and Bollob
We provide a new proof of Brylawski’s formula for the Tutte polynomial of the tensor product of two matroids. Our proof involves extending Tutte’s formula, expressing the Tutte...
