A Local Estimate for the Maximal Function in Lebesgue Spaces with EXP‐Type Exponents

open access: yesJournal of Function Spaces, Volume 2015, Issue 1, 2015., 2015
It is proven that if 1 ≤ p(·) < ∞ in a bounded domain Ω⊂Rn and if p(·) ∈ EXPa(Ω) for some a > 0, then given f ∈ Lp(·)(Ω), the Hardy‐Littlewood maximal function of f, Mf, is such that p(·)log(Mf) ∈ EXPa/(a+1)(Ω). Because a/(a + 1) < 1, the thesis is slightly weaker than (Mf) λp(·) ∈ L1(Ω) for some λ > 0. The assumption that p(·) ∈ EXPa(Ω) for some a > 0

Wirtinger inequality and nonlinear differential systems [PDF]

open access: yes, 1970
summary:Picone identity for a class of nonlinear differential equations is established and various qualitative results (such as Wirtinger-type inequality and the existence of zeros of first components of solutions) are obtained with the help of this new ...

Why diffusion‐based preconditioning of Richards equation works: Spectral analysis and computational experiments at very large scale

open access: yesNumerical Linear Algebra with Applications, Volume 31, Issue 1, January 2024.
Abstract We consider here a cell‐centered finite difference approximation of the Richards equation in three dimensions, averaging for interface values the hydraulic conductivity K=K(p)$$ K=K(p) $$, a highly nonlinear function, by arithmetic, upstream and harmonic means.

Picone identities for half-linear elliptic operators with p(x)-Laplacians and applications to Sturmian comparison theory

open access: yes, 2011
application/pdfPicone identities are established for a class of half-linear elliptic operators with p(x)-Laplacians, and Sturmian comparison theorems are obtained on the basis of the Picone identities. Generalizations to half-linear elliptic inequalities

Sturm comparison theorems for some elliptic type equations with damping and external forcing terms

open access: yes, 2015
In this paper we establish Picone-type inequalities for a pair of a damped linear elliptic equation and a forced nonlinear elliptic equation with damped term and give some Sturm comparison theorems via the Picone-type inequality. An oscillation result is

Positive solutions of inequality with $p$-Laplacian in exterior domains [PDF]

open access: yes, 2002
summary:In the paper the differential inequality \[\Delta _p u+B(x,u)\le 0,\] where $\Delta _p u=\div (\Vert \nabla u\Vert ^{p-2}\nabla u)$, $p>1$, $B(x,u)\in C(\mathbb{R}^{n}\times \mathbb{R},\mathbb{R})$ is studied.

Existence and Uniqueness of Positive Solutions to Fractional Problems of Brézis–Oswald-Type with Unbalanced Growths and Hardy Potentials

open access: yesFractal and Fractional
The aim of this paper is to establish the existence and uniqueness of positive solutions to the non-local Brézis–Oswald-type fractional problems that involve fractional (r,q)-Laplace operators and Hardy potentials. In particular, we observe an eigenvalue
