Existence Results for a critical fractional equation

open access: yes, 2016
We are concerned with existence results for a critical problem of Brezis-Nirenberg Type involving an integro-differential operator. Our study includes the fractional Laplacian. Our approach still applies when adding small singular terms.

Positive powers of the Laplacian in the half-space under Dirichlet boundary conditions

open access: yes, 2018
We present explicit formulas for solutions to nonhomogeneous boundary value problems involving any positive power of the Laplacian in the half-space. For non-integer powers the operator becomes nonlocal and this requires a suitable extension of Dirichlet-

C*-Structure and K-Theory of Boutet de Monvel's Algebra

open access: yes, 2001
We consider the norm closure $A$ of the algebra of all operators of order and class zero in Boutet de Monvel's calculus on a manifold $X$ with boundary $Y$.

Non-commutative residue of projections in Boutet de Monvel's calculus

open access: yes, 2007
Using results by Melo, Nest, Schick, and Schrohe on the K-theory of Boutet de Monvel's calculus of boundary value problems, we show that the non-commutative residue introduced by Fedosov, Golse, Leichtnam, and Schrohe vanishes on projections in the ...

Hopf's lemma for viscosity solutions to a class of non-local equations with applications

open access: yes, 2019
We consider a large family of non-local equations featuring Markov generators of L\'evy processes, and establish a non-local Hopf's lemma and a variety of maximum principles for viscosity solutions.

Interior and Boundary-Regularity for Fractional Harmonic Maps on Domains

open access: yes, 2011
We prove continuity on domains up to the boundary for n/2-polyharmonic maps into manifolds. Technically, we show how to adapt Helein's direct approach to the fractional setting.
