Abstract:
Let and let be a graded ideal in . We show that the upper bound of the multiplicity conjecture of Herzog, Huneke and Srinivasan holds asymptotically (i.e., for and all ) if belongs to any of the following large classes of ideals: - (1)
- radical ideals,
- (2)
- monomial ideals with generators in different degrees,
- (3)
- zero-dimensional ideals with generators in different degrees.
Surprisingly, our proof uses local techniques like analyticity, reductions, equimultiplicity and local results like Rees's theorem on multiplicities.
