摘要	We study the normalized solutions of the fractional nonlinear Schrodinger equations with combined nonlinearities (-Delta)(s)u = lambda u + mu vertical bar u vertical bar(q-2)u + vertical bar u vertical bar(p-2)u in R-N, and we look for solutions which satisfy prescribed mass integral(RN) vertical bar u vertical bar(2) = a(2), where N >= 2, s is an element of (0, 1), mu is an element of R and 2 < q < p < 2*(s) = 2N/(N - 2s). Under different assumptions on q < p, a > 0 and mu is an element of R, we prove some existence and nonexistence results about the normalized solutions. More specifically, in the purely L-2-subcritical case, we overcome the lack of compactness by virtue of the monotonicity of the least energy value and obtain the existence of ground state solution for mu > 0. While for the defocusing situation mu < 0, we prove the nonexistence result by constructing an auxiliary function. We emphasis that the nonexistence result is new even for Laplacian operator. In the purely L-2-supercritical case, we introduce a fiber energy functional to obtain the boundedness of the Palais-Smale sequence and get a mountain-pass type solution. In the combined-type cases, we construct different linking structures to obtain the saddle type solutions. Finally, we remark that we prove a uniqueness result for the homogeneous nonlinearity (mu = 0), which is based on the Morse index of ground state solutions.
