Moduli of elliptic surfaces of Kodaira dimension one fibered over rational curves
Dori Bejleri, Josiah Foster, Andres Fernandez Herrero +3
In this article, we construct an infinite sequence of irreducible components of Kollár--Shepherd-Barron (KSB-) moduli spaces of surfaces of arbitrarily large volumes, and describe…

Root stack valuative criterion for good moduli spaces
Dori Bejleri, Giovanni Inchiostro, Matthew Satriano
We prove a root stack valuative criterion for good moduli space maps and for gerbes for reductive groups under some mild assumptions on the residue characteristic. We give several…

Symmetric powers of null motivic Euler characteristic
Dori Bejleri, Stephen McKean
Let k be a field of characteristic not 2. We conjecture that if X is a quasi-projective k-variety with trivial motivic Euler characteristic, then SymX has trivial motivic Euler…
