Model-theoretic 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 -groups of model-theoretic structures, and computed 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 , Crawley-Boevey introduced the concept of a tree module and provided a combinatorial description of a basis for the space of h…

Model-theoretic of free modules over PIDs
Sourayan Banerjee, Amit Kuber
Motivated by KrajiÄek and Scanlon's definition of the Grothendieck ring of a first-order structure , we introduce the definition of -groups for vi…
