Model-theoretic $K_{1}$ for modules over semisimple rings: (weak) Morita invariance

Sourayan Banerjee, Amit Kuber

This paper is a sequel to a paper by the same authors, where they defined $K$ -groups of model-theoretic structures, and computed $K_{1}$ of free modules over PIDs. In this paper, we…

Generalised tree modules: Hom-sets and indecomposability

Annoy Sengupta, Amit Kuber

For a zero-relation algebra over a field $K$ , Crawley-Boevey introduced the concept of a tree module and provided a combinatorial description of a basis for the space of h…
