Exponential decay of correlations for a real valued dynamical system embedded in
Lisette Jager, Jules Maes, Alain Ninet
We study the real valued process defined by , where the are bounded. We aim at proving the decay of correlations for t…

Décroissance exponentielle des corrélations pour un système dynamique réel induit d'un système en dimension 2
Lisette Jager, Jules Maes, Alain Ninet
We study the discrete-time, real valued bounded process defined by a second order recurrence relation . We obtain the decay o…

Lower bounds for pseudodifferential operators with a radial symbol
Laurent Amour, Lisette Jager, Jean Nourrigat
In this paper we establish explicit lower bounds for pseudodifferential operators with a radial symbol. The proofs use classical Weyl calculus techniques and some useful, if not ce…

A remark concerning Feynman Kac formulas for the perturbed harmonic oscillator
L. Jager
We give the solution of certain parabolic evolution problems (time-depending perturbations of the heat equation for the harmonic oscillator) as explicit integrals on the Wiener spa…
