We construct and study universal spaces for birational invariants of algebraic varieties over algebraic closures of finite fields. 
Combinatorial Burnside groups
. We study the structure of combinatorial Burnside groups, which receive equivariant birational invariants of actions of finite groups on algebraic varieties.
On stable cohomology of central extensions of elementary abelian groups
We study when kernels of inflation maps associated to extraspecial p-groups in stable group cohomology are generated by their degree two components. This turns out to be true if the prime is large
Noether's problem and descent
We study Noether's problem from the perspective of torsors under linear algebraic groups and descent.
Irrationality of generic quotient varieties via Bogomolov multipliers
The Bogomolov multiplier of a group is the unramified Brauer group associated to the quotient variety of a faithful representation of the group. This object is an obstruction for the quotient variety
Galois module structure of square power classes for biquadratic extensions
This paper marks the first time that the Galois module structure of power classes of a field has been fully determined when the modular representation theory allows for an infinite number of
Galois module structure of the units modulo $$p^m$$ of cyclic extensions of degree $$p^n$$
Let p be prime, and n,m ∈ N. When K/F is a cyclic extension of degree p, we determine the Z/pZ[Gal(K/F )]-module structure of K/K m . With at most one exception, each indecomposable summand is cyclic

The subgroup of the Schur multiplier of a finite group G consisting of all cohomology classes whose restriction to any abelian subgroup of G is zero is called the Bogomolov multiplier of G. We prove
STABLE COHOMOLOGY OF GROUPS AND ALGEBRAIC VARIETIES
The notion of stable cohomology of algebraic varieties and, based on it, the analogous concept for finite and profinite groups are introduced. It is proved that the ordinary and stable cohomology
Valuations and local uniformization
We give the principal notions in valuation theory, the value group and the residue field of a valuation, its rank, the compositions of valuations, and we give some classical examples. Then we
