| contents | In this paper, we investigate normalized solutions of a fractional Gross-Pitaevskii equation, which arises in an attractive Bose-Einstein condensation consisting of $N$ bosons moving by Lévy flights. We prove that there exists a positive constant $N^*$, such that if $0<N<N^*$ and the Lévy index $α$ closed to $2$, the fractional Gross-Pitaevskii equation admits a local minimal normalized solution $u_α$ and a mountain pass solution $v_α$, but there does not exist positive local minimal solution if $N>N^*$ and $α$ closed to $2$. We also study the asymptotic behavior of $u_α$ and $v_α$ as $α\to 2_-$. |
