Exact structures and maximal canonically Jordan recoverable subcategories for modules over type algebras
Benjamin Dequêne, Sunny Roy
On one hand, exact structures were introduced by D. Quillen in the '70s. They can be defined as collections of short exact sequences in a fixed abelian category satisfying addition…

An exact structure approach to almost rigid modules over quivers of type
Thomas Brüstle, Eric J. Hanson, Sunny Roy +1
Let be the path algebra of a quiver of Dynkin type . The module category has a combinatorial model as the category of diagonals in a polygon w…
