Two formulas for the BR multiplicity
We prove a projection formula, expressing a relative Buchsbaum-Rim multiplicity in terms of corresponding ones over a module-finite algebra of pure degree, generalizing an old formula for the ordinary (Samuel) multiplicity. Our proof is simple in spirit: after the multiplicities are expressed as sum...
