讲座要点：
In this talk, we consider the well-posedness and large deviations for stochastic shallow water equations. Firstly, using regularization method and bilinear estimates in Bourgain space, the well-posednesss of stochastic Camassa-Holm equation with additive Wiener noise is established. Secondly, using the weak convergence method, the large deviation for the solutions of stochastic modified Camassa-Holm equation with multiplicative Wiener noise is obtained. Lastly, we consider the well-posedness and large deviation for the solutions of stochastic PDEs with Levy noise. The results can be applied to some types of stochastic shallow water equations, such as stochastic Burgers equation, stochastic b-family equation, stochastic modified Novikov equation and stochastic $\mu$-Hunter-Saxton equation.
