On endomorphisms of affine spaces and the Jacobian problem

Alexander Borisov, Ofer Gabber, Adrian Vasiu

Let $p$ be a prime. We provide examples which show that étale endomorphisms of affine planes over an algebraically closed field $k$ of characteristic $p$ can have fibers of arbitra…

On lifting representations and actions on curves of the metacyclic groups $C_{p^{s}} ⋊ C_{m}$

Huy Dang, Adrian Vasiu

For a prime $p$ , a pair $(s, m) \in N^{2}$ with $m$ relatively prime to $p$ , a homomorphism $χ : C_{m} \to Aut (C_{p^{s}})$ , and an algebraically closed field $k$ …

Infinite transitivity of tame groups of automorphisms of affine spaces

Alexander Borisov, Ofer Gabber, Adrian Vasiu

For positive integers $n$ and $m$ , we study the actions of the groups of tame automorphisms of the $n$ -dimensional affine spaces over finite fields on ordered subsets of $m$ points…

On the factorizations of integers via division algorithms for polynomials

Guram Donadze, Adrian Vasiu

We introduce and study several conditions related to the factorization problem of composite numbers. For this purpose, we employ cyclotomic polynomials, Sylvester resultants, and t…

Matrix invertible extensions over commutative rings. Part III: Hermite rings

Grigore Călugăreanu, Horia F. Pop, Adrian Vasiu

We reobtain and often refine prior criteria due to Kaplansky, McGovern, Roitman, Shchedryk, Wiegand, and Zabavsky--Bilavska and obtain new criteria for a Hermite ring to be an \tex…
