Skew category algebras and modules on ringed finite sites

Mawei Wu, Fei Xu

Let $C$ be a small category. We investigate ringed sites $(C, R)$ on $C$ and the resulting module categories $\mathfrak{M}{\rm od}\text{-}\ma…

On indefinite $k$ -universal integral quadratic forms over number fields

Zilong He, Yong Hu, Fei Xu

An integral quadratic lattice is called indefinite $k$ -universal if it represents all integral quadratic lattices of rank $k$ for a given positive integer $k$ . For $k \geq 3$ , we pr…
