Retracts and algebraic properties of cut algebras
arXiv:1608.04973 · doi:10.1016/j.ejc.2017.11.002
Abstract
We study cut algebras which are toric rings associated to graphs. The key idea is to consider suitable retracts to understand algebraic properties and invariants of such algebras like being a complete intersection, having a linear resolution, or the Castelnuovo-Mumford regularity. Throughout the paper, we discuss several examples and pose some problems as well.
