Maximum principles for boundary-degenerate second-order linear elliptic differential operators

open access: yes, 2013
We prove weak and strong maximum principles, including a Hopf lemma, for smooth subsolutions to equations defined by linear, second-order, partial differential operators whose principal symbols vanish along a portion of the domain boundary.

Best constants in bipolar L^p-Hardy-type Inequalities

open access: yes, 2022
In this work we prove sharp $L^p$ versions of multipolar Hardy inequalities in the case of a bipolar potential and $p\geq 2$, which were first developed in the case $p=2$ by Cazacu (CCM 2016) and Cazacu&Zuazua (Studies in phase space analysis with ...

Strong maximum principles for infinite implicit parabolic systems [PDF]

open access: yes, 2014
In this paper we prove a theorem on strong maximum principles for infinite implicit systems of parabolic differential-functional inequalities together with nonlocal inequalities with functionals in (n + 1)-dimensional sets more general than the ...

Higher order evolution inequalities involving Leray-Hardy potential singular on the boundary [PDF]

open access: yes
We consider a higher order (in time) evolution inequality posed in the half ball, under Dirichlet type boundary conditions. The involved elliptic operator is the sum of a Laplace differential operator and a Leray-Hardy potential with a singularity ...

Boundedness and pointwise differentiability of weak solutions to quasi-linear elliptic differential equations and variational inequalities [PDF]

open access: yes, 1994
summary:The local boundedness of weak solutions to variational inequalities (obstacle problem) with the linear growth condition is obtained. Consequently, an analogue of a theorem by Reshetnyak about a.e\.

The nonlinear N-membranes evolution problem [PDF]

open access: yes, 2008
The parabolic N-membranes problem for the p-Laplacian and the complete order constraint on the components of the solution is studied in what concerns the approximation, the regularity and the stability of the variational solutions.

A minimization problem involving a fractional Hardy-Sobolev type inequality

open access: yes, 2019
In this work, we obtain an existence of nontrivial solutions to a minimization problem involving a fractional Hardy-Sobolev type inequality in the case of inner singularity. Precisely, for $\lambda>0$ we analyze the attainability of the optimal constant $

Weighted Hardy-Rellich type inequalities: improved best constants and symmetry breaking

open access: yes
When studying the weighted Hardy-Rellich inequality in $L^2$ with the full gradient replaced by the radial derivative the best constant becomes trivially larger or equal than in the first situation. Our contribution is to determine the new sharp constant
