Jacobian Conjecture via Differential Galois Theory [PDF]

open access: diamondSymmetry, Integrability and Geometry: Methods and Applications, 2019
We prove that a polynomial map is invertible if and only if some associated differential ring homomorphism is bijective. To this end, we use a theorem of Crespo and Hajto linking the invertibility of polynomial maps with Picard-Vessiot extensions of ...

Generalized differential Galois theory [PDF]

open access: bronzeTransactions of the American Mathematical Society, 2008
A Galois theory of differential fields with parameters is developed in a manner that generalizes Kolchin's theory. It is shown that all connected differential algebraic groups are Galois groups of some appropriate differential field extension.

LARGE FIELDS IN DIFFERENTIAL GALOIS THEORY [PDF]

open access: yesJournal of the Institute of Mathematics of Jussieu, 2017

Differential Galois theory of infinite dimension [PDF]

open access: bronzeNagoya Mathematical Journal, 1996
This paper is the second part of our work on differential Galois theory as we promised in [U3]. Differential Galois theory has a long history since Lie tried to apply the idea of Abel and Galois to differential equations in the 19th century (cf. [U3], Introduction). When we consider Galois theory of differential equation, we have to separate the finite

DIFFERENTIAL GALOIS THEORY AND INTEGRABILITY [PDF]

open access: greenInternational Journal of Geometric Methods in Modern Physics, 2009
This paper is an overview of our works that are related to investigations of the integrability of natural Hamiltonian systems with homogeneous potentials and Newton's equations with homogeneous velocity independent forces. The two types of integrability obstructions for these systems are presented.

Descent for differential Galois theory of difference equations. Confluence and q-dependency [PDF]

open access: green, 2011
The present paper contains two results that generalize and improve constructions of Hardouin and Singer. In the case of a derivation, we prove that the parametrized Galois theory for difference equations constructed by Hardouin and Singer can be ...

Quantum integrable systems and differential Galois theory [PDF]

open access: green, 1996
This paper is devoted to a systematic study of quantum completely integrable systems (i.e., complete systems of commuting differential operators) from the point of view of algebraic geometry. We investigate the eigenvalue problem for such systems and the
