%0 Journal Article %T On a fractional Nirenberg problem, part II: existence of solutions %A Tianling Jin %A YanYan Li %A Jingang Xiong %J Mathematics %D 2013 %I arXiv %R 10.1093/imrn/rnt260 %X This paper is a continuation of our earlier work "[T. Jin, Y.Y. Li and J. Xiong, On a fractional Nirenberg problem, part I: blow up analysis and compactness of solutions, to appear in J. Eur. Math. Soc.]", where compactness results were given on a fractional Nirenberg problem. We prove two existence results stated there. We also obtain a fractional Aubin inequality. %U http://arxiv.org/abs/1309.4666v1
