The ambiguity index of an equipped finite group

F. A. Bogomolov, Vik. S. Kulikov

In \cite{Ku0}, the ambiguity index $a_{(G, O)}$ was introduced for each equipped finite group $(G, O)$ . It is equal to the number of connected components of a Hurwitz space parametri…

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…
