We study the dynamical properties of blowup solutions to the focusing L2-supercritical nonlinear fractional Schrödinger equation i∂tu − (−Δ)su = −|u|αu on , where , , and the initial data is radial with the critical Sobolev exponent sc. To this end, we establish a compactness lemma related to the equation by means of the profile decomposition for bounded sequences in . As a result, we obtain the -concentration of blowup solutions with bounded -norm and the limiting profile of blowup solutions with critical -norm.
