Symmetric subcategories, tilting modules and derived recollements

Hongxing Chen, Changchang Xi

For any good tilting module $T$ over a ring $A$ , there exists an $n$ -symmetric subcategory $E$ of a module category such that the derived category of the endomorphism rin…

Invariant algebras of matrices and symmetric polynomials of partitions

Changchang Xi, Jinbi Zhang

For a field $R$ of characteristic $p \geq 0$ and a matrix $c$ in the full $n \times n$ matrix algebra $M_{n} (R)$ over $R$ , let $S_{n} (c, R)$ be the centralizer algebra of $c$ in $M_{n} (R)$ .…
