%0 Journal Article %T On the orbital stability of fractional Schr£żdinger equations %A Yonggeun Cho %A Gyeongha Hwang %A Hichem Hajaiej %A Tohru Ozawa %J Mathematics %D 2013 %I arXiv %X We show the existence of ground state and orbital stability of standing waves of fractional Schr\"{o}dinger equations with power type nonlinearity. For this purpose we establish the uniqueness of weak solutions. %U http://arxiv.org/abs/1302.2719v2
