Stabilizer Reduction for Derived Stacks and Applications to Sheaf-Theoretic Invariants
Jeroen Hekking, David Rydh, Michail Savvas
We construct a canonical stabilizer reduction for any derived -algebraic stack over as a sequence of derived Kirwan blow-ups, under mild natural…

Virtual Riemann-Roch Theorems for Almost Perfect Obstruction Theories
Michail Savvas
This is the third in a series of works devoted to constructing virtual structure sheaves and -theoretic invariants in moduli theory. The central objects of study are almost perf…
