Resumen de Isolated singularities for a semilinear equation for the fractional Laplacian arising in conformal geometry

Azahara de la Torre Pedraza, María del Mar González Nogueras

• We consider radial solutions with an isolated singularity for a semilinear equation involving the fractional Laplacian. In conformal geometry, this is equivalent to the study of singular metrics with constant fractional curvature (singular fractional Yamabe problem). Our main ideas are: first, to set up the problem into a natural geometric framework; and second, to reduce the problem to a non-local ODE for which we are able to perform some kind of phase portrait study.
