Description
We will review some results on the construction and interaction of solitary waves for nonlinear Schrödinger equations with power nonlinearity. After discussing briefly the well-known question of stability of single solitary waves, we will present a short proof of existence of multi-solitary waves in the case of weak interactions. Then, in the sub-critical and super-critical cases, we will show the existence of multi-solitary waves with logarithmic distance in time (case of strong interaction).
