Consider the nonlinear Schrodinger equation u(t) - iDELTAu = f(u). For
f(u) = +/-\u\1+p, +/-i\u\1+p, +/-u\u\p (p > 0), and the Dirichlet bou
ndary or nonlinear boundary (including the Neumann boundary and the Ro
bin boundary) conditions, we establish the local estimates for the tim
e t to the solutions of the initial-boundary value problems. Being bas
ed up on these estimates, we investigate the blowing-up properties of
the solutions.
