,Density Estimate in Small Time for Jump Processes with Singular Lévy Measures,In this chapter, we study the asymptotic behavior of the transition density for processes of jump type as the time parameter . tends to 0. We use Picard’s duality method, which allows us to obtain the lower and upper bounds of the density even for the case where the support of Lévy measure is very singular.

,Variational Calculus for a Lévy Process Based on a Lie Group,The tools of the stochastic calculus of variations are constructed for Poisson processes on a Lie group, and the corresponding analysis on the Lie-Wiener space is recovered as the limiting case of this construction.

Sharp Laplace Asymptotics for a Hyperbolic SPDE,In this paper we prove a precise asymptotic estimate for Laplace type functionals of a certain class of hyperbolic SPDEs. We use a large deviation principle, the stochastic Taylor’s expansion introduced by Azencott, and some methods of representation and estimation for our stochastic partial differential equation.

Damped Logarithmic Sobolev Inequality on the Wiener Space,Using Girsanov and the change of variables formula on an abstract Wiener space, we prove damped versions of logarithmic Sobolev and Poincaré inequalities.
