Random walks in symmetric random media
Russian Mathematical Surveys, 1983The paper shortly writes down several conclusions. A connection between such random walks and special so-called quasi-diffusion processes is given ({\S} 1). A general quasi-diffusion process depends on some distribution. The convergence of a sequence of distributions implies convergence of the corresponding sequence of finite-dimensional distribution ...

Statistical Stability for Transport in Random Media
Multiscale Modeling & Simulation, 2019Summary: We go back to the analysis of the transport of (classical or quantum) particles in time-dependent random media as proposed in [\textit{F. Poupaud} and \textit{A. Vasseur}, J. Math. Pures Appl. (9) 82, No. 6, 711--748 (2003; Zbl 1035.82037)], where the convergence of the expectation of solutions of the Liouville equation (resp., Wigner equation)

Proceedings, 2014
I will present an introduction to the mathematical theory of wave propagation in heterogeneous media with uncertain micro-scale, modelled as random media. I will summarize the scattering effects in such media and how to mitigate them in order to obtain high fidelity imaging results.

International Journal of Engineering Science, 1984
A Dyson equation is used for comparisons of different approximations for the calculation of the wave number of the ensemble averaged linear harmonic response of a discrete random medium. The Lax quasicrystalline approximation and its several ''self-consistent'' generalizations are compared. Formal arguments for the order of the errors incurred in these

Diffusions and random walks in random media
1983We formulate and analyze briefly some problems that arise when diffusion processes evolve in a random medium. We also consider some systems of interacting Brownian particles and examine their collective behavior.
