This thesis is organised in two relatively independent chapters.Chapter 1 is devoted to the study of some mathematical problems arising in the theory of hydrodynamic turbulence. Our results focus on questions related to the large deviations principle (LDP), Gallavotti–Cohen type symmetry, and ergodicity (existence and uniqueness of a stationary measure and its mixing properties) for a family of randomly forced PDE’s. We establish the LDP for parabolic PDE’s, such as the Navier–Stokes system or the complex Ginzburg–Landau equation, perturbed by a random kick force. Then we extend this result to the case of the damped nonlinear wave equation driven by a spatially regular white noise, by proving a local LDP. We establish a Gallavotti–Cohen typ...
