Moduli stacks of Serre stable representations in tilting theory
Daniel Chan, Boris Lerner
We introduce a new moduli stack, called the Serre stable moduli stack, which corresponds to studying families of point objects in an abelian category with a Serre functor. This all…

A recollement approach to Geigle-Lenzing weighted projective varieties
Boris Lerner, Steffen Oppermann
We introduce a new method for expanding an abelian category and study it using recollements. In particular, we give a criterion for the existence of cotilting objects. We show, usi…
