Cohen-Macaulay clutters with combinatorial optimization properties and parallelizations of normal edge ideals

Luis A. Dupont, Enrique Reyes-Espinoza, Rafael H. Villarreal

Let C be a uniform clutter and let I=I(C) be its edge ideal. We prove that if C satisfies the packing property (resp. max-flow min-cut property), then there is a uniform Cohen-Maca…
