Automorphisms of the affine Cremona group [PDF]
, 2013 We show that every automorphism of the group Gn := Aut(An) of polynomial automorphisms of complex affine n-space An = Cn is inner up to field automorphisms when restricted to the subgroup TGn of tame automorphisms.

Basic automorphisms of cartan foliations covered by fibrations
Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2021 Background. This work is devoted to the study of basic automorphisms AB (M,F) groups of Cartan foliations (M,F) covered by fibrations, and to finding sufficient conditions for the existence of a finite-dimensional Lie group structure in AB (M,F) .

Normal Supercharacter Theory [PDF]
Discrete Mathematics & Theoretical Computer Science, 2020 There are three main constructions of supercharacter theories for a group G. The first, defined by Diaconis and Isaacs, comes from the action of a group A via automorphisms on our given group G.

Action of automorphisms on irreducible characters of symplectic groups [PDF]
Journal of Algebra, 2016 Assume G is a finite symplectic group Sp 2 n ( q ) over a finite field F q of odd characteristic. We describe the action of the automorphism group Aut ( G ) on the set Irr ( G ) of ordinary irreducible characters of G.

Primitive ideals and automorphisms of quantum matrices. [PDF]
, 2007 Let K be a field and q be a nonzero element of K that is not a root of unity. We give a criterion for (0) to be a primitive ideal of the algebra O-q(M-m,M-n) of quantum matrices.

Extensions of automorphisms of self-similar groups [PDF]
Journal of group theroy, 2018 In this work, we study automorphisms of synchronous self-similar groups and the existence of extensions to continuous automorphisms over the closure of these groups with respect to the depth metric.

Normal automorphisms of relatively hyperbolic groups
, 2010 An automorphism of a group G is normal if it fixes every normal subgroup of G setwise. We give an algebraic description of normal automorphisms of relatively hyperbolic groups.
