Möbius and coboundary polynomials for matroids
DESIGNS CODES AND CRYPTOGRAPHY(2021)
摘要
We study how some coefficients of two-variable coboundary polynomials can be derived from Betti numbers of Stanley–Reisner rings. We also explain how the connection with these Stanley–Reisner rings forces the coefficients of the two-variable coboundary polynomials and Möbius polynomials to satisfy certain universal equations.
