Abstract
Using virial estimates we study the temporal evolution of localized so lutions to the Raman-extended derivative nonlinear Schrodinger (R-EDNL S) equation, with a particular emphasis on collapse and non-collapse. By means of a Lagrangian approach, we investigate the possibility of r ealizing a finite-time self-similar collapse as it appears in solution s to the usual critical nonlinear Schrodinger (CNLS) equation.
