Non-relativistic conformal symmetries and Newton-Cartan structures
Christian Duval, Péter A. Horvathy
This article provides us with a unifying classification of the conformal infinitesimal symmetries of non-relativistic Newton-Cartan spacetime. The Lie algebras of non-relativistic…
Galilean Isometries
Christian Duval
We introduce three nested Lie algebras of infinitesimal `isometries' of a Galilei space-time structure which play the rôle of the algebra of Killing vector fields of a relativistic…
Barriers for the reduction of transport due to the EXB drift in magnetized plasmas
Natalia Tronko, Michel Vittot, Cristel Chandre +2
We consider a 1 1/2degrees of freedom Hamiltonian dynamical system, which models the chaotic dynamics of charged test-particles in a turbulent electric field, across the confining…
Note on the Transition to Intermittency for the exponential of the Square of a Steinhaus Series
Philippe Mounaix, Pierre Collet
Intermittency of as is investigated on a -dimensional torus , when is a finite Steinhaus series o…
