摘要	We study the existence and orbital stability of standing waves of nonlinear fractional Schrodinger equations with a general nonlinear term iu(t)-(-Delta)(s)u + f(u) = 0, (t,x) is an element of R+ x R-N. We investigate the minimizing problem with L-2 -constraint: E-alpha = inf {1/2 integral(RN) vertical bar(-Delta)(s/2)u vertical bar(2) dx - integral(RN) F(vertical bar u vertical bar)dx vertical bar u is an element of H-s (R-N), parallel to u parallel to(2)(L)(2)((RN )()) = alpha }. The existence and non-existence of global minimizers with respect to E-alpha are established for all possible values of alpha. Under some general assumptions on the nonlinear term f(u), there exists a constant alpha(0) >= 0 such that a global minimizer exists for E-alpha for all alpha > alpha(0), and there is no global minimizer with respect to E-alpha for all 0 < alpha < alpha(0). By virtue of concentration-compactness argument and the strict subadditivity of E-alpha, the strong convergence of minimizing sequence is obtained. Moreover, we present some criteria which determine alpha(0) = 0 or alpha(0) > 0, and the existence of global minimizers for E-alpha 0. Besides, we show the orbital stability of the global minimizers set. Finally, we prove that an energy minimizer is a least action solution by Pohozaev identity.
