報(bào)告摘要：

             Intuitively, inttermittency refers to a state of the system with random noise in which the high peak is rare but real. In mathematics, it can be described in terms of moment asymptotics of the system. Compared to the parabolic Anderson equation, the inttermittency for hyperbolic An derson equation is much harder and less investigated due to absence of Feynman-Kac formula that links the parabolic Anderson equation to Brownian motions. I will report some recent progress in the regimes of Stratonovich. In particular, I will show how the large deviation technique is combined with Laplace-Fourier transforms and Malliavin calculus to achieve the precise moment asymptotics. The talk is based on part of a collaborating work joint with Hu, Y. Z. and has been accepted by Ann. Probab.
