Construction of multi-soliton solutions for the $L^2$-supercritical gKdV and NLS equations

Multi-soliton solutions, i.e. solutions behaving as the sum of N given solitons as t \to +\infty , were constructed for the L^2 critical and subcritical (NLS) and (gKdV) equations in previous works (see [Merle, F.: Construction of solutions with exactly k blow-up points for the Schrödinger equation ...
