Description
Radiative transport equations and other macroscopic
kinetic models are widely used to describe multiple scattering
of wave energy in random media. They account for the incoherent
wave energy, and their validity is associated with the randomness of the
wave field. The opposite regime is homogenization - here, the wave field
has a deterministic macroscopic limit. I will try to describe the transition
from one regime to the other, and understand which one is more
generic. This is a joint work with G. Bal, T. Chen and T. Komorowski.
