Fibre sum functors and the bimodule Ext (English)
0 references
Let \(A\) be a finite-dimensional algebra over an algebraically closed field \(k\). Representations of the bimodule \(\text{Ext}^1_A(-,-)\) and fibre sum functors both provide techniques for the investigation of module categories for finite-dimensional algebras. The main result gives a relation between these two constructions.NEWLINENEWLINEFor the entire collection see [Zbl 0974.00038].
