Gorenstein liaison for toric ideals of graphs

Published 13 Dec 2017 in math.AG, math.AC, and math.CO | (1712.04726v1)

Abstract: A central question in liaison theory asks whether every Cohen-Macaulay, graded ideal of a standard graded K-algebra belongs to the same G-liaison class of a complete intersection. In this paper we answer this question positively for toric ideals defining edge subrings of bipartite graphs.
