Abstract. In a recent series of papers, Da Lio and Riviere introduced the concept of fractional harmonic map to understand the Wente inequality in one dimension. We will report on some results where we study on one hand the Ginzburg-Landau approximation of half-harmonic maps into spheres and on the other hand the regularity in one dimension of super-critical fractional harmonic maps. We will also introduce a ow of such maps into spheres and homogeneous spaces and study global weak solutions.
