Probability density for a hyperbolic SPDE with time dependent coefficients
ESAIM: Probability and Statistics, Tome 11 (2007), pp. 365-380.

We prove the existence and smoothness of density for the solution of a hyperbolic SPDE with free term coefficients depending on time, under hypoelliptic non degeneracy conditions. The result extends those proved in Cattiaux and Mesnager, PTRF 123 (2002) 453-483 to an infinite dimensional setting.
