A special case of positivity (II)

Research output: Contribution to journalArticlepeer-review

Abstract

In this note we prove the following special case of Serre's conjecture on Intersection Multiplicity: Let (R, m) be a regular local ring and let P, Q be two prime ideals such that l(R/(P + Q)) < ∞, dim A/P + dim R/Q = dim R and dimension of G m(R/P) ⊗ Gm(R) G m(R/Q) < 2. Then Χ(R/P,R/Q} ≥ e m(R/P)e m(R/Q); here e m(T) denotes the Hilbert-Samuel multiplicity for any finitely generated module T with respect to m.
