【 摘 要 】
We study the following nonlinear Schrodinger equation iu(t) = -Delta u + V(x)u - a vertical bar u vertical bar(q)u, (t,x) epsilon R-1 x R-2, where a > 0, q epsilon (0, 2), and V(x) is some type of trapping potential. For any fixed a > a* := parallel to Q parallel to(2)(2), where Q is the unique (up to translations) positive radial solution of Delta u - u + u(3) = 0 in R-2, by directly using constrained variational method and energy estimates we present a detailed analysis of the concentration and symmetry breaking of standing waves for the above equation as q NE arrow 2.
