Abstract:In the first part of the talk, we construct an asymptotic preserving (AP) numerical method for the defocusing Davey–Stewartson II equation in the semiclassical limit. First, we introduce the WKB ansatz and obtain a new system for the complex-valued amplitude function and real-valued phase function, respectively...
