Brauer groups and crepant resolutions

Vladimir Baranovsky, Tihomir Petrov

We suggest a twisted version of the categorical McKay correspondence and prove several results related to it.

Unramified Brauer groups of finite simple groups of Lie type $A_{ℓ}$

Fedor Bogomolov, Jorge Maciel, Tihomir Petrov

We study the subgroup B_0(G) of H^2(G,Q/Z) consisting of all elements which have trivial restrictions to every Abelian subgroup of G. The group B_0(G) serves as the simplest nontri…

Rationality of moduli of elliptic fibrations with fixed monodromy

Fedor Bogomolov, Tihomir Petrov, Yuri Tschinkel

We prove rationality results for moduli spaces of elliptic K3 surfaces and elliptic rational surfaces with fixed monodromy groups.
