Symbolic powers in weighted oriented graphs

30 Jun 2020 Mandal Mousumi Pradhan Dipak Kumar

Let $D$ be a weighted oriented graph with the underlying graph $G$ when vertices with non-trivial weights are sinks and $I(D), I(G) $ be the edge ideals corresponding to $D$ and $G,$ respectively. We give explicit description of the symbolic powers of $I(D)$ using the concept of strong vertex covers... (read more)
