Stability and Instability of Solitary Wave Solutions of a Nonlinear Dispersive System of Benjamin-Bona-Mahony Type
2000 Mathematics Subject Classification: 35B35, 35B40, 35Q35, 76B25, 76E30.This paper concerns the orbital stability and instability of solitary waves of the system of coupling equations of Benjamin-Bona-Mahony
type. By applying the abstract results of Grillakis, Shatah and Strauss and detailed spectral analysis, we obtain the existence and stability of the solitary waves.Partially Supported by Grant MM-810/98 of MESC and by Scientefic Research Grant 19/12.03.2003 of Shumen University
Stability of periodic traveling waves for complex modified Korteweg-de Vries equation
We study the existence and stability of periodic traveling-wave solutions for
complex modified Korteweg-de Vries equation. We also discuss the problem of
uniform continuity of the data-solution mapping.Comment: Latex, 20 page
Spectral stability for subsonic traveling pulses of the Boussinesq `abc' system
We consider the spectral stability of certain traveling wave solutions of the
Boussinesq `abc' system. More precisely, we consider the explicit
like solutions of the form (\vp(x-w t), \psi(x- w t)=(\vp, const. \vp),
exhibited by M. Chen (1998) and we provide a complete rigorous characterization
of the spectral stability in all cases for which
