A mean field equation as limit of nonlinear diffusions with fractional Laplacian operators

Sylvia Serfaty, Juan Luis Vázquez

Research output: Contribution to journalArticle


In the limit of a nonlinear diffusion model involving the fractional Laplacian we get a "mean field" equation arising in superconductivity and superfluidity. For this equation, we obtain uniqueness, universal bounds and regularity results. We also show that solutions with finite second moment and radial solutions admit an asymptotic large time limiting profile which is a special self-similar solution: the "elementary vortex patch".
