A-hypergeometric Systems and Embedded Primes

Abstract

The holonomic rank of an A-hypergeometric system HA(β) is conjectured to be independent of the parameter vector β if and only if the toric ideal IA is Cohen Macaulay. We attack this conjecture by explicitly constructing more than vol (A) many linearly independent hypergeometric functions for parameters β coming from embedded primes of certain initial ideals… (More)
