Toric ideals which are determinantal
Abstract
Given any equigenerated monomial ideal I with the property that the defining ideal J of the fiber cone F(I) of I is generated by quadratic binomials, we introduce a matrix such that the set of its binomial 2-minors is a generating set of J. In this way, we characterize the fiber cone of sortable and Freiman ideals.
