In this paper, by variational methods and the profile decomposition of bounded sequences in H 1 we study the existence of stable standing waves for the Schrödinger-Choquard equation with an L 2-critical nonlinearity. Our results extend some earlier results.

In this paper, we study the dynamics of blow-up solutions for the nonlinear Schrödinger-Choquard equationWe first show existence of blow-up solutions and obtain a sharp threshold mass of MSC: 35Q55; 35A15
