Simplicial complexes which are minimal Cohen-Macaulay
Yanyan Wang, Tongsuo Wu
Let $\D$ be a -dimensional pure -simplicial complex over vertex set . In this paper, it is proved that holds true if $\D$ is minimal Cohen-Macaulay. It is als…
The Cohen-Macaulay Property of -ideals
A-Ming Liu, Jin Guo, Tongsuo Wu
For positive integers , let where . For a pure -simplicial complex such that an…
Remarks on two theorems in linear algebra
Yifan Ren, Tongsuo Wu
In this note, we use the concept of a polynomial ring to give an elementary proof to Cayley-Hamilton Theorem. We also give an elementary proof to Birkhoff theorem on Bi-stochastic…
On reduction number of products of ideals
Dancheng Lu, Tongsuo Wu
Let be a standard graded algebra over an infinite field and a finitely generated $\ZZ$-graded -module. Let be graded ideals of . The fun…
A construction of sequentially Cohen-Macaulay graphs
A-Ming Liu, Tongsuo Wu
For every simple graph , a class of multiple clique cluster-whiskered graphs is introduced, and it is shown that all graphs are vertex decomposable, thus the i…
Boolean graphs are unmixed and vertex decomposable
A-Ming Liu, Tongsuo Wu
For each Boolean graph , it is proved that both and its complement graph are vertex decomposable. It is also proved that is an unmixed graph, thus…
