Typical dropping asymptotics of quasiclassical approximations to solutions of the nonlinear Schrödinger equation

Sergej Melikhov, Bulat Suleimanov, Azamat Shavlukov

Formal asymptotics are substantiated that describe typical dropping cusp singularity of quasiclassical approximations to solutions of two cases of the integrable nonlinear Schrödin…
