Regularity estimates for fractional orthotropic p-Laplacians of mixed order

open access: yesAdvances in Nonlinear Analysis, 2022
We study robust regularity estimates for a class of nonlinear integro-differential operators with anisotropic and singular kernels. In this paper, we prove a Sobolev-type inequality, a weak Harnack inequality, and a local Hölder estimate.

Nonlinear elliptic equations with high order singularities [PDF]

open access: yes, 2016
We study non-variational degenerate elliptic equations with high order singular structures. No boundary data are imposed and singularities occur along an {\it a priori} unknown interior region. We prove that positive solutions have a universal modulus of

Solvability and microlocal analysis of the fractional Eringen wave equation

open access: yes, 2017
We discuss unique existence and microlocal regularity properties of Sobolev space solutions to the fractional Eringen wave equation, initially given in the form of a system of equations in which the classical non-local Eringen constitutive equation is ...

Remark on the analyticity of the fractional Fokker-Planck equation

open access: yesAdvances in Nonlinear Analysis
In this note, we study the Cauchy problem of the fractional Fokker-Planck equation. We prove that the solution to the Cauchy problem enjoys the analytic smoothing effect with an L2{L}^{2} initial datum for positive time, and the evolution of the analytic

Non-oriented solutions of the eikonal equation [PDF]

open access: yes, 2008
We study a new formulation for the eikonal equation |grad u| =1 on a bounded subset of R^2. Instead of a vector field grad u, we consider a field P of orthogonal projections on 1-dimensional subspaces, with div P in L^2. We prove existence and uniqueness

Regularity of optimal mapping between hypercubes

open access: yesAdvanced Nonlinear Studies, 2023
In this note, we establish the global C3,α{C}^{3,\alpha } regularity for potential functions in optimal transportation between hypercubes in Rn{{\mathbb{R}}}^{n} for n≥3n\ge 3. When n=2n=2, the result was proved by Jhaveri.

Small solitons and multisolitons in the generalized Davey-Stewartson system

open access: yesAdvances in Nonlinear Analysis, 2022
By introducing and solving a new cross-constrained variational problem, a one-to-one correspondence from the prescribed mass to frequency of soliton is established for the generalized Davey-Stewartson system in two-dimensional space. Orbital stability of
