Special ACM and CMX Seminar
Numerical Methods for Fractional Laplacians
Professor Gabriel Acosta, Department of Mathematics, Univeristy of Buenos Aires
The aim of this talk is to review some recent numerical techniques to deal with equations involving fractional laplacian operators. We focus mainly on finite element approaches for two different definitions associated to the fractional laplacian: the so-called integral version, involving a hypersingular kernel and the spectral version of the operator. Some regularity results, needed for the error analysis, are also discussed.
