A density theorem for parameterized differential Galois theory [PDF]

open access: yesPacific Journal of Mathematics, 2014
We study parameterized linear differential equations with coefficients depending meromorphically upon the parameters. As a main result, analogously to the unparameterized density theorem of Ramis, we show that the parameterized monodromy, the ...

LARGE FIELDS IN DIFFERENTIAL GALOIS THEORY [PDF]

open access: yesJournal of the Institute of Mathematics of Jussieu, 2020
AbstractWe solve the inverse differential Galois problem over differential fields with a large field of constants of infinite transcendence degree over $\mathbb{Q}$. More generally, we show that over such a field, every split differential embedding problem can be solved.

DIFFERENTIAL GALOIS THEORY AND INTEGRABILITY [PDF]

open access: yesInternational 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.

Non-integrability on AdS3 supergravity backgrounds

open access: yesJournal of High Energy Physics, 2020
We investigate classical integrability on two recently discovered classes of back- grounds in massive IIA supergravity. These vacua are of the form AdS3 × S2 × ℝ × CY2, they preserve small N $$ \mathcal{N} $$ = (0, 4) supersymmetry and are associated ...

Differential Galois Theory and Integration [PDF]

open access: yes, 2021
In this paper, we present methods to simplify reducible linear differential systems before solving. Classical integrals appear naturally as solutions of such systems. We will illustrate the methods developed in a previous paper on several examples to reduce the differential system.

A new discretization of the Euler equation via the finite operator theory [PDF]

open access: yesOpen Communications in Nonlinear Mathematical Physics
We propose a novel discretization procedure for the classical Euler equation, based on the theory of Galois differential algebras and the finite operator calculus developed by G.C. Rota and collaborators.

Some definable Galois theory and examples [PDF]

open access: yes, 2016
We make explicit certain results around the Galois correspondence in the context of definable automorphism groups, and point out the relation to some recent papers dealing with the Galois theory of algebraic differential equations when the constants are ...
