An exact structure approach to almost rigid modules over quivers of type $A$

Thomas BrÃ¼stle, Eric J. Hanson, Sunny Roy +1

Let $A$ be the path algebra of a quiver of Dynkin type $A_{n}$ . The module category $mod A$ has a combinatorial model as the category of diagonals in a polygon $S$ w…

Sequences of ICE-closed subcategories via preordered $I ¨ ^{- 1}$ -rigid modules

Eric J. Hanson

Let $I^$ be a finite-dimensional basic algebra. Sakai recently used certain sequences of image-cokernel-extension-closed (ICE-closed) subcategories of finitely generated $I^$ -modul…
