I am studying the following paper.
Manoussos Grillakis, Jalal Shatah, and Walter Strauss, Stability theory of solitary waves in the presence of symmetry. I, J. Funct. Anal. 74 (1987), no. 1, 160–197.
This is a highly cited paper that has given rise to a lot of Mathematics. But as beginner I am finding it hard to appreciate the the abstract mechanisms in their proof and their result. My question is can somebody provide me some papers where they used the results of GSS in some concrete situations?. I know that they discuss some applications at the back end of their paper. I am asking can I find more?. I hope my question is appropriate here.
