Ordinary and symbolic powers of edge ideals of weighted oriented graphs
Arindam Banerjee, Kanoy Kumar Das, S. Selvaraja
Let be a weighted oriented graph and be its edge ideal. In this paper, we show that all the symbolic and ordinary powers of coincide…
Symbolic powers of vertex cover ideals
S Selvaraja
Let be a finite simple graph and denote its cover ideal in a polynomial ring over a field . In this paper, we show that all symbolic powers of cover ideals o…
Symbolic powers of certain cover ideals of graphs
Arvind Kumar, Rajiv Kumar, Rajib Sarkar +1
In this paper, we compute the regularity and Hilbert series of symbolic powers of the cover ideal of a graph when is either a crown graph or a complete multipartite graph.…
Upper bounds for the regularity of powers of edge ideals of graphs
A. V. Jayanthan, S. Selvaraja
Let be a finite simple graph and denote the corresponding edge ideal. In this paper, we obtain upper bounds for the Castelnuovo-Mumford regularity of in terms o…
