Dirichlet problems involving the Hardy-Leray operators with multiple polars

open access: yesAdvances in Nonlinear Analysis, 2023
Our aim of this article is to study qualitative properties of Dirichlet problems involving the Hardy-Leray operator ℒV≔−Δ+V{{\mathcal{ {\mathcal L} }}}_{V}:= -\Delta +V, where V(x)=∑i=1mμi∣x−Ai∣2V\left(x)={\sum }_{i=1}^{m}\frac{{\mu }_{i}}{{| x-{A}_{i}| }

On singular elliptic equations with measure sources [PDF]

open access: yes, 2016
We prove existence of solutions for a class of singular elliptic problems with a general measure as source term whose model is $$\begin{cases} -\Delta u = \frac{f(x)}{u^{\gamma}} +\mu & \text{in}\ \Omega, u=0 &\text{on}\ \partial\Omega, u>0 &\text{on}\

A note on the complete rotational invariance of biradial solutions to semilinear elliptic equations [PDF]

open access: yes, 2010
We investigate symmetry properties of solutions to equations of the form $$ -\Delta u = \frac{a}{|x|^2} u + f(|x|, u)$$ in R^N for $N \geq 4$, with at most critical nonlinearities.

A functionally-analytic method for modelling axial-symmetric flows of ideal fluid

open access: yesDemonstratio Mathematica, 2019
We consider axial-symmetric stationary flows of the ideal incompressible fluid as an important case of potential solenoid fields. We use an integral expression of the Stokes flow function via the corresponding complex analytic function for solving a ...

Semilinear elliptic equations in thin regions with terms concentrating on oscillatory boundaries [PDF]

open access: yes, 2018
In this work we study the behavior of a family of solutions of a semilinear elliptic equation, with homogeneous Neumann boundary condition, posed in a two-dimensional oscillating thin region with reaction terms concentrated in a neighborhood of the ...

Nonlinear singular problems with indefinite potential term

open access: yes, 2020
We consider a nonlinear Dirichlet problem driven by a nonhomogeneous differential operator plus an indefinite potential. In the reaction we have the competing effects of a singular term and of concave and convex nonlinearities.
