We investigate wave collapse in the generalized nonlinear Schr\"odinger (NLS) equation and in the presence of a non vanishing background. Through the use of virial identities, we establish a new criterion for blow-up.

Abstract
We investigate wave collapse in the generalized nonlinear Schr\"odinger (NLS) equation and in the presence of a non vanishing background. Through the use of virial identities, we establish a new criterion for blow-up.File in questo prodotto:
