The $\circ$ operation and $*$ operation of Cohen-Macaulay bipartite graphs

Yulong Yang, Guangjun Zhu, Yijun Cui +1

Let $G$ be a finite simple graph with the vertex set $V$ and let $I_{G}$ be its edge ideal in the polynomial ring $S = K [x_{V}]$ . In this paper, we compute the depth and the Cas…

The $\circ$ operation and $*$ operation of fan graphs

Guangjun Zhu, Yijun Cui, Yulong Yang +1

Let $G$ be a finite simple graph on the vertex set $V$ and let $I_{G}$ denote its edge ideal in the polynomial ring $S = K [x_{V}]$ . In this paper, we compute the depth and the C…

Freiman Borel type ideals

Guangjun Zhu, Yakun Zhao, Shiya Duan +1

An equigenerated monomial ideal $I$ in the polynomial ring $S = K [x_{1}, \dots, x_{n}]$ is a Freiman ideal if $μ (I^{2}) = ℓ (I) μ (I) - (2 ℓ ( I ))$ where $ℓ (I)$ is the analytic spre…
