摘要
We extend the sortability concept to monomial ideals which are not necessarily generated in one degree and as an application we obtain normal Cohen-Macaulay toric rings attached to vertex cover ideals of graphs. Moreover, we consider a construction on a graph called a clique multiwhiskering which always produces vertex cover ideals with componentwise linear powers. & COPY; 2023 Elsevier Inc.
