Speaker: Xia Chen (University of Tennessee) Topic: Intermittency for hyperbolic Anderson equations with time-independent Gaussian noise: Stratonovich regime. Abstract: Recently, a precise intermittency for the hyperbolic Anderson model has been established in Ito-Skorohod regime. In this talk, we discuss the same problem in Stratonovich regime. Our approach provides new ingredient on representation and computation for Stratonovich […]
