Abstract: | AbstractUsing two related parameters, ζ and γ, we extend the recursion for com- puting the Tutte polynomial of any graph to the computation of the Tutte polynomial of any multigraph. With this recursion, we found explicit formulae for several fami- lies of multigraphs. In particular, the Tutte polynomials of some cyclic multigraphs, 2?tree multigraphs, and any l?bridge multigraph. |
