Fractional Diffusion in Lipschitz Domains: Regularity and Approximation
A talk in the Nonlocal Equations: Analysis and Numerics series by
Ricardo Nochetto from Maryland
| Abstract: |
This talk describes the formulation of linear fractional diffusion
via the integral Dirichlet Laplacian, the regularity of solutions
on bounded domains and the approximation by finite element methods.
It emphasizes recent research about Besov regularity on Lipschitz
domains, BPX preconditioning, a priori error estimates in quasi-uniform
and graded meshes, and local error estimates. It also discusses extensions
to quasi-linear fractional problems
