Enhancement of the Zakharov-Glassey's method for Blow-up in nonlinear Schrodinger equations

In this paper we give a sharper sufficient condition for blow-up of the solution to a nonlinear Schrodinger equation with free/Stark/quadratic potential by improving the well known Zakharov-Glassey's method.
