Sumario:We develop in the language of graph homomorphisms the connection between the Tutte polynomial and the state models of statistical physics. • The Tutte polynomial and homomorphism numbers. • Spin models and edge coloring models. • Connection matrices and the characterization of graph invariants arising from spin models. • Homomorphism numbers and invariants of the cycle matroid of a graph. • Graph homomorphism numbers as evaluations of graph polynomials. • Other graph polynomials from counting graph homomorphisms such as the independence polynomial, the Averbouch–Godlin–Makowsky polynomial, and the Tittmann–Averbouch–Makowsky polynomial.
