Embedding of vector-valued Morrey spaces and separable differential operators [PDF]
Bulletin of Mathematical Sciences, 2019 The paper is the first part of a program devoted to the study of the behavior of operator-valued multipliers in Morrey spaces. Embedding theorems and uniform separability properties involving E-valued Morrey spaces are proved.

Local regularity for an anisotropic elliptic equation [PDF]
Calculus of Variations and Partial Differential Equations, 2020 AbstractWe establish the interior Hölder continuity for locally bounded solutions, and the Harnack inequality for non-negative continuous solutions to a class of anisotropic elliptic equations with bounded and measurable coefficients, whose prototype equation is $$\begin{aligned} u_{xx}+\varDelta _{q,y} u=0\quad {\text { locally in }}{\mathbb {R ...

Time-delay regularization of anisotropic diffusion and image processing [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2005 Summary: We study a time-delay regularization of the anisotropic diffusion model for image denoising of \textit{P. Perona} and \textit{J. Malik} [IEEE Trans. Pattern Anal. Mach. Intell. 12, 629--639 (1990)], which has been proposed by \textit{M. Nitzberg} and \textit{T. Shiota} [IEEE Trans. Pattern Anal. Mach. Intell. 14, 826--835 (1998)].

Nonlinear anisotropic parabolic equations in Lm
Arab Journal of Mathematical Sciences, 2014 In this paper, we give a result of regularity of weak solutions for a class of nonlinear anisotropic parabolic equations with lower-order term when the right-hand side is an Lm function, with m being ”small”.

Regularity Criterion for the Nematic Liquid Crystal Flows in Terms of Velocity
Abstract and Applied Analysis, 2014 We study the regularity criterion for the 3D nematic liquid crystal flows in the framework of anisotropic Lebesgue space. More precisely, we proved some sufficient conditions in terms of velocity or the fractional derivative of velocity in one direction.

Positive solutions for parametric (p(z),q(z))-equations
Open Mathematics, 2020 We consider a parametric elliptic equation driven by the anisotropic (p,q)(p,q)-Laplacian. The reaction is superlinear. We prove a “bifurcation-type” theorem describing the change in the set of positive solutions as the parameter λ\lambda moves in ℝ+=(0,

Isomorphism theorems for some parabolic initial-boundary value problems in Hörmander spaces
Open Mathematics, 2017 In Hörmander inner product spaces, we investigate initial-boundary value problems for an arbitrary second order parabolic partial differential equation and the Dirichlet or a general first-order boundary conditions.
