Cohen-Macaulay edge-weighted graphs of girth $5$ or greater

Truong Thi Hien

Let $G_{ω}$ be an edge-weighted graph whose underlying graph is $G$ . In this paper, we enlarge the class of Cohen-Macaulay edge-weighted graphs $G_{ω}$ by classifying completely them w…

Depth of powers of edge ideals of Cohen-Macaulay trees

Nguyen Thu Hang, Truong Thi Hien, Thanh Vu

Let $I$ be the edge ideal of a Cohen-Macaulay tree of dimension $d$ over a polynomial ring $S = k [x_{1}, \dots, x_{d}, y_{1}, \dots, y_{d}]$ . We prove that for all $t \geq 1$ , $$\op…
