Very large solutions for the fractional Laplacian: Towards a fractional Keller–Osserman condition

Advances in Nonlinear Analysis, 2017
We look for solutions of (-△)s⁢u+f⁢(u)=0{{\left(-\triangle\right)}^{s}u+f(u)=0} in a bounded smooth domain Ω, s∈(0,1){s\in(0,1)}, with a strong singularity at the boundary. In particular, we are interested in solutions which are L1⁢(Ω){L^{1}(\Omega)} and

Sobolev spaces with non-Muckenhoupt weights, fractional elliptic operators, and applications [PDF]

, 2018
We propose a new variational model in weighted Sobolev spaces with non-standard weights and applications to image processing. We show that these weights are, in general, not of Muckenhoupt type and therefore the classical analysis tools may not apply ...

Kirchhoff–Hardy Fractional Problems with Lack of Compactness

Advanced Nonlinear Studies, 2017
This paper deals with the existence and the asymptotic behavior of nontrivial solutions for some classes of stationary Kirchhoff problems driven by a fractional integro-differential operator and involving a Hardy potential and different critical ...

Generalised Fractional Evolution Equations of Caputo Type [PDF]

, 2017
This paper is devoted to the study of generalised time-fractional evolution equations involving Caputo type derivatives. Using analytical methods and probabilistic arguments we obtain well-posedness results and stochastic representations for the ...

Elliptic Pre-Complexes, Hodge-like Decompositions and Overdetermined Boundary-Value Problems

Forum of Mathematics, Sigma
We solve a problem posed by Calabi more than 60 years ago, known as the Saint-Venant compatibility problem: Given a compact Riemannian manifold, generally with boundary, find a compatibility operator for Lie derivatives of the metric tensor. This problem

Universal Constraints on the Location of Extrema of Eigenfunctions of Non-Local Schr\"odinger Operators [PDF]

, 2019
We derive a lower bound on the location of global extrema of eigenfunctions for a large class of non-local Schr\"odinger operators in convex domains under Dirichlet exterior conditions, featuring the symbol of the kinetic term, the strength of the ...

Crack Theory with Singularities at the Boundary [PDF]

, 2003
2002 Mathematics Subject Classification: 35S15, 35J70, 35J40, 38J40We investigate crack problems, where the crack boundary has conical singularities. Elliptic operators with two-sided elliptic boundary conditions on the plus and minus sides of the crack ...

Nonlinear elliptic equations with self-adjoint integro-differential operators and measure data under sign condition on the nonlinearity

Advanced Nonlinear Studies
We study the existence problem for semilinear equations (E): −Au = f(⋅, u) + μ, with Borel measure μ and operator A that generates a symmetric Markov semigroup.
