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

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 ...

The nonlinear N-membranes evolution problem [PDF]

, 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

, 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

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

GENERALIZED MAXIMUM PRINCIPLES FOR SOME DIFFERENTIAL INEQUALITIES WITH APPLICATIONS

Far East Journal of Mathematical Sciences (FJMS), 2018
In this paper we consider several types of differential equations and discuss the maximum principle for them. In general, the maximum principle tells us that the maximum value of the function, which is a solution of a differential equation, is attained ...

Ostrowski Type Inequalities and Hardy Inequalities With Boundary Terms Related to the Generalized Greiner Operator

, 2015
In this paper, we first show a representation formula related to the generalized Greiner operator by an improved method. Then using the representation formula and L ∞ norm of the horizontal gradient, we establish Ostrowski type inequalities in the ball ...
