题目:Riemann-Hilbert方法在Sasa-Satsuma方程中的应用

 

摘要:The initial value problem for the Sasa-Satsuma equation is transformed to a 3 ×3 matrix Riemann-Hilbert problem with the help of the corresponding Lax pair. Two distinct factorizations of the jump matrix and a decomposition of the vector-valued function ρ(k) are given, from which the long-time asymptotics for the Sasa-Satsuma equation with decaying initial data is obtained by using the nonlinear steepest descent method.
