Stability and asymptotic stability in the energy space of the sum of N solitons for subcritical gKdV equations
Yvan Martel, Frank Merle, Tai-Peng Tsai
We prove in this paper the stability and asymptotic stability in H^1 of a decoupled sum of N solitons for the subcritical generalized KdV equations (1<p<5).…

Relaxation of Excited States in Nonlinear Schrödinger Equations
Tai-Peng Tsai, Horng-Tzer Yau
We consider a nonlinear Schrödinger equation in with a bounded local potential. The linear Hamiltonian is assumed to have two bound states with the eigenvalues satisfying so…

Stable Directions for Excited States of Nonlinear Schrödinger Equations
Tai-Peng Tsai, Horng-Tzer Yau
We consider nonlinear Schrödinger equations in . Assume that the linear Hamiltonians have two bound states. For certain finite codimension subset in the space of initial data…
