Universal localizations of $d$-homological pairs
Abstract
Let be an algebraically closed field and a finite dimensional -algebra. The universal localization of with respect to a set of morphisms between finitely generated projective -modules always exists. Moreover, when is hereditary, Krause and \v{S}\v{t}ov\'i\v{c}ek proved that the universal localizations of are in bijective correspondence with various natural structures. Taking inspiration from an alternative definition of universal localizations involving a triangulated subcategory of , we introduce a higher analogue of universal localizations. That is, fixing a positive integer , we define universal localizations of -homological pairs with respect to suitable wide subcategories of . When gldim, we show that the result by Krause and \v{S}\v{t}ov\'i\v{c}ek has a (partial) higher analogue and that such universal localizations exist with respect to any choice of with the required properties. Moreover, we show that in this setup, the base case of our definition and the definition of classic universal localization coincide.
