We study minimal reductions of edge ideals of graphs containing a unique even cycle, and determine restrictions on the coefficients of the generators of these minimal reductions.

We introduce a concept of a W- graph ideal in a Coxeter group.The main goal of this paper is to describe how to construct a W- graph from a given W- graph ideal. The principal application of this idea...

This paper studies properties of simplicial complexes with the equal-ity I(m) = Im
for a given m ≥ 2. The main results are combinatorial characteriza-tions of such complexes in the two-dimensio...
