On the Noether Problem for torsion subgroups of tori

We consider the Noether Problem for stable and retract rationality for the sequence of $d$-torsion subgroups $T[d]$ of a torus $T$, $d\geq 1$. We show that the answer to these questions only depends

The Ekedahl Invariants for finite groups

The Space of Morphisms on Projective Space

The theory of moduli of morphisms on P^n generalizes the study of rational maps on P^1. This paper proves three results about the space of morphisms on P^n of degree d > 1, and its quotient by the

Rationality problem of GL4 group actions

A constructive approach to Noether's problem

A general method is developed to attack Noether's Problem constructively by trying to find minimal bases consisting of rational invariants which are quotients of polynomials of small degrees. This

$\tilde{B_0}$-invariant of groups

. The Bogomolov multiplier of a group G introduced by Bogomolov in 1988. After that in 2012, Moravec introduced an equivalent definition of the Bogomolov multiplier. In this paper we generalized the

Normal forms in differential Galois theory for the classical groups

. Let G be a classical group of dimension d and let a = ( a 1 ,...,a d ) be differential indeterminates over a differential field F of characteristic zero with algebraically closed field of constants C .

On Unramified Brauer groups of finite groups

The Bogomolov multiplier B0(G) of a finite group G is the subgroup of the Schur multiplier H(G,Q/Z) consisting of the cohomology classes which vanishes after restricting to any abelian subgroup of G.
