Triangulations of polygons and stacked simplicial complexes: separating their Stanley-Reisner ideals

Commutative Algebra 2022-08-30 v3

Abstract

A triangulation of a polygon has an associated Stanley-Reisner ideal. We obtain a full algebraic and combinatorial understanding of these ideals, and describe their separated models. More generally we do this for stacked simplicial complexes, in particular for stacked polytopes.
