Homomorphism and sigma polynomials
By establishing a connection between the sigma polynomial and the homomorphism polynomial, many of the proofs for computing the sigma polynmial are simplified, the homomorphism polynomial can be identified for several new classes of graphs, and progress can be made on identifying homomorphism polyno...

| Summary: | By establishing a connection between the sigma polynomial
and the homomorphism polynomial, many of the proofs for computing the
sigma polynmial are simplified, the homomorphism polynomial can be
identified for several new classes of graphs, and progress can be made
on identifying homomorphism polynomials. |
