### On LDP and inviscid hydrodynamical equations

Seminar Room 1, Newton Institute

#### Abstract

We will present some recent results jointly proven with H. Bessaih about a Large Deviations Principle for solutions to some stochastic hydrodynamical equations when the viscosity coefficient converges to 0 and the (multiplicative) noise is multiplied by the square root of the viscosity. The good rate function is described in terms of the solution to a deterministic inviscid control equation, which is more irregular in the space variable than the solution to the stochastic evolution equation. This forces us to use either a smaller space or a weaker topology than the "natural ones". The proof uses the weak convergence approach to LDP.#### Video
