Resumen de Almgren’s frequency formula for an extension problem related to the anisotropic fractional Laplacian

Raimundo Leitão

• We consider the anisotropic version of an extension problem studied by Caffarelli and Silvestre. We present the anisotropic fractional Laplacian and prove the Almgren’s frequency formula obtained by Caffarelli and Silvestre for the anisotropic case.
