The conjectures of Artin-Tate and Birch-Swinnerton-Dyer [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2022
We provide two proofs that the conjecture of Artin-Tate for a fibered surface is equivalent to the conjecture of Birch-Swinnerton-Dyer for the Jacobian of the generic fibre.

An extension to the planar Markus–Yamabe Jacobian conjecture

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
We extend the planar Markus–Yamabe Jacobian conjecture to differential systems having Jacobian matrix with eigenvalues with negative or zero real parts.

Attacking Jacobian Problem Using Resultant Theory

open access: yesمجلة بغداد للعلوم, 2022
     This paper introduces a relation between resultant and the Jacobian determinant by generalizing Sakkalis theorem from two polynomials in two variables to the case of (n) polynomials in (n) variables. This leads us to study the results of the type:

Exact verification of the strong BSD conjecture for some absolutely simple abelian surfaces

open access: yesComptes Rendus. Mathématique, 2022
Let $X$ be one of the $28$ Atkin–Lehner quotients of a curve $X_0(N)$ such that $X$ has genus $2$ and its Jacobian variety $J$ is absolutely simple. We show that the Shafarevich–Tate group $\Sha (J/\mathbb{Q})$ is trivial.

JACOBIAN CONJECTURE, TWO-DIMENSIONAL CASE

open access: yesПроблемы анализа, 2016
The Jacobian Conjecture was first formulated by O. Keller in 1939. In the modern form it supposes injectivity of the polynomial mapping f: R^n → R^n (C^n → C^n) provided that jacobian J_f ≡ const ≠ 0.

Polynomial Automorphisms, Deformation Quantization and Some Applications on Noncommutative Algebras

open access: yesMathematics, 2022
This paper surveys results concerning the quantization approach to the Jacobian Conjecture and related topics on noncommutative algebras. We start with a brief review of the paper and its motivations.

THE JACOBIAN CONJECTURE: STRUCTURE OF KELLER MAPPINGS

open access: yesПроблемы анализа, 2019
The Jacobian conjecture was first formulated by O. N. Keller in 1939. In the modern form it supposes injectivity of the polynomial mapping f : R n → R n (C n → C n ) under the assumption that Jf ≡ const 6= 0.

STRUCTURE OF KELLER MAPPINGS, TWO-DIMENSIONAL CASE

open access: yesПроблемы анализа, 2017
A Keller map is a polynomial mapping ƒ : Rⁿ → Rⁿ (or Cⁿ → Cⁿ) with the Jacobian J_ƒ ≡ const ≠ 0. The Jacobian conjecture was first formulated by O. N. Keller in 1939. In the modern form it supposes injectivity of a Keller map. Earlier, in the case n = 2,
