Group actions and invariants in algebras of generic matrices
Zinovy Reichstein, Nikolaus Vonessen
We show that the fixed elements for the natural GL_m-action on the universal division algebra UD(m,n) of m generic n x n matrices form a division subalgebra of degree n, assuming n…

Birational isomorphisms between twisted group actions
Zinovy Reichstein, Angelo Vistoli
Let X be an algebraic variety with a generically free action of a connected algebraic group G. Given an automorphism u of G, we will denote by X^u the same variety X with the G-act…
