On the set of associated radicals of powers of monomial ideals
Nguyen Thu Hang, Truong Thi Hien
Let be a monomial ideal in a polynomial ring. In this paper, we study the asymptotic behavior of the set of associated radical ideals of the (symbolic) powers of . We show t…

Depth stability of cover ideals
Mai Phuoc Binh, Nguyen Thu Hang, Truong Thi Hien +1
Let R = K[x1,...,xr] be a polynomial ring over a field K. Let G be a graph with vertex set {1,...,r} and let J be the cover ideal of G. We give a sharp bound for the stability inde…

Regularity of powers of cover ideals of unimodular hypergraphs
Nguyen Thu Hang, Tran Nam Trung
Let $\H$ be a unimodular hypergraph over the vertex set and let be the cover ideal of $\H$ in the polynomial ring . We show that $\reg J(\H)^s$ i…
