Regularity of Powers and symbolic powers of edge ideals of cubic circulant graphs

Nguyen Thu Hang, My Hanh Pham, Thanh Vu

We compute the regularity of powers and symbolic powers of edge ideals of all cubic circulant graphs. In particular, we establish Conjecture of Minh for cubic circulant graphs.

Log-concavity of the independence polynomials of $W_{p}$ graphs

Do Trong Hoang, Vadim E. Levit, Eugen Mandrescu +1

Let $G$ be a graph of order $n$ . For a positive integer $p$ , $G$ is said to be a $W_{p}$ graph if $n \geq p$ and every $p$ pairwise disjoint independent sets of $G$ are con…
