    Injective generation for tensor rings.

  • Abstract:
    In 2019 Rickard introduced a condition for rings, called injective generation and proved that if injectives generate for a finite dimensional algebra, then this algebra has finite finitistic dimension. The aim of this talk is to show that given a ring R and a "sufficiently nice" R-bimodule M, then injectives generate for R if and only if injectives generate for the tensor ring of R by M. This is based on joint work with Chrysostomos Psaroudakis.
