The Brauer Group of
Niven Achenjang, Deewang Bhamidipati, Aashraya Jha +2
We determine the Brauer group of the Deligne-Mumford stack , the moduli space of elliptic curves with a marked -torsion subgroup over bases of arithmetic inter…
General base change for relative Du Bois complexes
Caleb Ji, Sándor Kovács
A partial answer is given to a question raised by Kovács and Taji in arxiv:2307.07192, namely that the relative Du Bois complex of a family parametrized by a non-singular curve co…
Duality of differential operators and algebraic de Rham cohomology
Caleb Ji, Casimir Kothari, Oliver Li +3
Given a smooth proper morphism , we introduce a certain derived category where morphisms are permitted to be -linear differential operators.…
Effectivity for bounds on points of good reduction in the moduli space of hypersurfaces
Caleb Ji
Let be a finite set of primes. For sufficiently large and , Lawrence and Venkatesh proved that in the moduli space of hypersurfaces of degree in , the…
