On Quiver Grassmannians and Orbit Closures for Gen-Finite Modules

Abstract We show that endomorphism rings of cogenerators in the module category a finite-dimensional algebra A admit canonical tilting module, whose tilted B is related to by recollement. Let M be gen-finite -module, meaning there are only finitely many indecomposable modules generated . Using tilts algebras suitable associated , and resulting recollements, we construct desingularisations orbit closure quiver Grassmannians thus generalising all results from previous work Crawley-Boevey second author 2017. provide dual versions key results, order also treat cogen-finite modules.
