Frobenius Categories over a Triangular Matrix Ring and Comma Categories

Dancheng Lu, Panpan Xie

We introduce the dual notions of $E (X, M, Y)$ and $M (X, M, Y)$ , and investigate when they have enough injective objects or p…

The $a_{0}$ -invariants of powers of a two-dimensional squarefree monomial ideal

Lizhong Chu, Dancheng Lu

Let $Δ$ be an one-dimensional simplicial complex on ${1, 2, \dots, s}$ and $S$ the polynomial ring $K [x_{1}, \dots, x_{s}]$ over a field $K$ . The explicit formula for $a_{0} (S / I_{Δ}^{n})$ is…
