摘要:
We study the following nonlinear Schrodinger equation with a fourth-order dispersion term?(2)u - beta?u = g(u) in R(N)in the positive and zero mass regimes: in the former, N >= 2 and beta > -2 root m, where m > 0 depends on g; in the latter, N >= 3 and beta > 0. In either regimes, we find an infinite sequence of solutions under rather generic assumptions about g; if N = 2 in the positive mass case, or N =4 in the zero mass case, we need to strengthen such assumptions. Our approach is variational.
