Cohen-Macaulay permutation graphs
P. V. Cheri, Deblina Dey, Akhil K +2
In this article, we characterize Cohen-Macaulay permutation graphs. In particular, we show that a permutation graph is Cohen-Macaulay if and only if it is well-covered and there ex…
On Cohen-Macaulay posets of dimension two and permutation graphs
Rizwan Jahangir, Dharm Veer
We characterize Cohen-Macaulay posets of dimension two; they are precisely the shellable and strongly connected posets of dimension two. We also give a combinatorial description of…
Green-Lazarsfeld property for Segre product of Hibi rings
Dharm Veer
In this article, we prove that if a Hibi ring satisfies property , then its Segre product with a polynomial ring in finitely many variables also satisfies property . When…
Polyocollection ideals and primary decomposition of polyomino ideals
Carmelo Cisto, Francesco Navarra, Dharm Veer
In this article, we study the primary decomposition of some binomial ideals. In particular, we introduce the concept of polyocollection, a combinatorial object that generalizes the…
