A density theorem in parametrized differential Galois theory [PDF]

open access: bronzePacific 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 ...

Differential Galois Theory and Hopf Algebras for Lie Pseudogroups [PDF]

open access: goldAxioms
According to a clever but rarely quoted or acknowledged work of E. Vessiot that won the prize of the Académie des Sciences in 1904, “Differential Galois Theory” (DGT) has mainly to do with the study of “Principal Homogeneous Spaces” (PHSs) for finite ...

Integrability of stochastic birth-death processesviadifferential Galois theory [PDF]

open access: hybrid, 2020
Stochastic birth-death processes are described as continuous-time Markov processes in models of population dynamics. A system of infinite, coupled ordinary differential equations (the so-called master equation) describes the time-dependence of the ...

Poisson Groups and Differential Galois Theory of Schroedinger Equation on the Circle [PDF]

open access: green, 2008
We combine the projective geometry approach to Schroedinger equations on the circle and differential Galois theory with the theory of Poisson Lie groups to construct a natural Poisson structure on the space of wave functions (at the zero energy level ...

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 ...

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.

Meromorphic Non-Integrability of Several 3D Dynamical Systems

open access: yesEntropy, 2017
In this paper, we apply the differential Galoisian approach to investigate the meromorphic non-integrability of a class of 3D equations in mathematical physics, including Nosé–Hoover equations, the Lü system, the Rikitake-like system and Rucklidge ...
