A Riemann-Hilbert approach for the Degasperis-Procesi equation [PDF]
A. Boutet de Monvel, D. ShepelskyWe present an inverse scattering transform approach to the Cauchy problem on the line for the Degasperis--Procesi equation $u_t-u_{txx}+3\omega u_x+4uu_x=3u_xu_{xx}+uu_{xxx}$ in the form of an associated Riemann-Hilbert problem. This approach allows us to give a representation of the solution to the Cauchy problem, which can be efficiently used in studying its long-time behavior.View original: http://arxiv.org/abs/1107.5995
