Title：Critical exponent for Schroedinger equation with nonlinear Neumann
boundary conditions

Abstract：Schroedinger equation with the nonlinear Neumann boundary condition of
the order $q$ is considered in a scale invariant space. We show that if
$q>2$ and the data are in the homogeneous Sobolev space of $L^2$ type of
the order $-1/(q-1) + 1/2$ (which is a scale invariant space), then
small data global existence of solutions holds. We also show when $q=2$
or $1<q<2$, solutions blow up in finite time. This is a joint work with
C. Li, T. Ogawa and T. Sato.
