Abstract:

This article is concerned with blow-up solutions of the Cauchy problem of critical nonlinear Schr¨odinger equation with a Stark potential. By using the variational characterization of corresponding ground state, the limiting behavior of blow-up solutions with critical and small super-critical mass are obtained in the natural energy space ∑ ={u H1; ∫RN |x|2|u|2dx < +∞}. Moreover, an interesting concentration property of the blow-up solutions with critical mass is gotten, which reads that |u(t, x)|2 → ||Q||2 Lδx=x1 as tT.

Key words: Nonlinear Schr¨odinger equation, Stark potential, blow-up solution, limiting behavior, mass concentration
