We will present two types of applications of Malliavin Calculus to SPDEs: - Absolute continuity and smoothness of the density for the law of the solution at a fixed time of the stochastic heat and wave equations, assuming a nondegeneracy condition on the diffusion coefficient.
- Existence and uniqueness of a solution for the one-dimensional stochastic heat equation driven by a space-time white noise, when the diffusion coefficient is bounded away from zero and the drift is irregular (regularization effect).
Prerequisites: Good working knowledge of Ito stochastic calculus and basic properties of Gaussian processes. Some basic properties of the stochastic heat and wave equations. | |
