Transverse instability for periodic waves of KP-I and Schrödinger equations
Sevdzhan Hakkaev, Milena Stanislavova, Atanas Stefanov
We consider the quadratic and cubic KP - I and NLS models in dimensions with periodic boundary conditions. We show that the spatially periodic travelling waves (with period $…

Asymptotic stability of small gap solitons in the nonlinear Dirac equations
Dmitry E. Pelinovsky, Atanas Stefanov
We prove dispersive decay estimates for the one-dimensional Dirac operator and use them to prove asymptotic stability of small gap solitons in the nonlinear Dirac equations with qu…
