Abstract
We give a method for computing the syzygies of the coordinate ring R of an affine toric variety. We show how the method works for dimension one and tw o cases, Cohen-Macaulay semigroups, and for computing minimal generators of the defining ideal. We show how to compute the depth of R and generalize a criterion for Cohen-Macaulayness. (C) 2000 Academic Press.
