Let X be a complete n-dimensional simplicial toric variety with homogeneous coordinate ring S. We study the multi graded Hilbert function H-Y of reduced 0-dimensional sub schemes Y in X. We provide explicit formulas and prove non-decreasing and stabilization properties of H-Y when Y is a 0-dimensional complete intersection in X. We apply our results to computing the dimension of some evaluation codes on 0-dimensional complete intersection in simplicial toric varieties. (C) 2016 Elsevier Inc. All rights reserved.
