2-recollements of singualrity categories and Gorenstein defect categories over triangular matrix algebras

Huanhuan Li, Dandan Yang, Yuefei Zheng +1

Let $T = (A, M, 0, B)$ be a triangular matrix algebra with its corner algebras $A$ and $B$ Artinian and $_{A} M_{B}$ an $A$ - $B$ -bimodule. The 2-recollement structures for singularity categor…

Every group is the maximal subgroup of a naturally occurring free idempotent generated semigroup

Victoria Gould, Dandan Yang

Gray and Ruskuc have shown that any group G occurs as the maximal subgroup of some free idempotent generated semigroup IG(E) on a biordered set of idempotents E, thus resolving a l…
