Abstract:
In this talk, we consider the well-posedness of stochastic S-KdV driven by multiplicative noises in H_x^1×H_x^1. To get the local well-posedness, we first develop the bilinear and trilinear Bourgain norm estimates of the nonlinear terms with b∈(0,1/2). Then, to overcome the lack of the maximum functional estimate, we introduce a series of approximation equations with localized nonlinear terms, which are also cutted-off in both the physical and the Fourier space. By limitations, these approximation equations will help us get a priori estimate in the Bourgain space and finish the proof of the global well-posedness of the initial system.
