Locally free twisted sheaves of infinite rank

Aise Johan de Jong, Max Lieblich, Minseon Shin

We study twisted vector bundles of infinite rank on gerbes, giving a new spin on Grothendieck's famous problem on the equality of the Brauer group and cohomological Brauer group. W…

The $Br = Br^{'}$ question for some classifying stacks

Minseon Shin

In this paper we consider the $Br = Br^{'}$ question for classifying stacks by various group schemes. These are algebraic stacks that do not necessarily admit a fini…

The cohomological Brauer group of a torsion $G_{m}$ -gerbe

Minseon Shin

Let $S$ be a scheme and let $π : G \to S$ be a $G_{m, S}$ -gerbe corresponding to a torsion class $[G]$ in the cohomological Brauer group $\mathrm{Br}'(S)…
