The Method of Fischer‐Riesz Equations for Elliptic Boundary Value Problems

Journal of Complex Analysis, Volume 2013, Issue 1, 2013., 2013
We develop the method of Fischer‐Riesz equations for general boundary value problems elliptic in the sense of Douglis‐Nirenberg. To this end we reduce them to a boundary problem for a (possibly overdetermined) first‐order system whose classical symbol has a left inverse.

Nonzero positive solutions of a multi-parameter elliptic system with functional BCs

, 2017
We prove, by topological methods, new results on the existence of nonzero positive weak solutions for a class of multi-parameter second order elliptic systems subject to functional boundary conditions. The setting is fairly general and covers the case of

Sturm-Picone type theorems for nonlinear differential systems

Electronic Journal of Differential Equations, 2015
In this article, we establish a Picone-type inequality for a pair of first-order nonlinear differential systems. By using this inequality, we give Sturm-Picone type comparison theorems for these systems and a special class of second-order half-linear ...

A Brézis–Oswald-Type Result for the Fractional (r, q)-Laplacian Problems and Its Application

Fractal and Fractional
This study derives the uniqueness of positive solutions to Brézis–Oswald-type problems involving the fractional (r,q)-Laplacian operator and discontinuous Kirchhoff-type coefficients.

Nonlocal problems with critical Hardy nonlinearity

, 2018
By means of variational methods we establish existence and multiplicity of solutions for a class of nonlinear nonlocal problems involving the fractional p-Laplacian and a combined Sobolev and Hardy nonlinearity at subcritical and critical growth.Comment:

Multivariable approximate Carleman-type theorems for complex measures

, 2007
We prove a multivariable approximate Carleman theorem on the determination of complex measures on ${\mathbb{R}}^n$ and ${\mathbb{R}}^n_+$ by their moments. This is achieved by means of a multivariable Denjoy--Carleman maximum principle for quasi-analytic

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

Fractal 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

Well-posedness of a model of nonhomogeneous compressible-incompressible fluids

, 2016
We propose a model of a density-dependent compressible-incompressible fluid, which is intended as a simplified version of models based on mixture theory as, for instance, those arising in the study of biofilms, tumor growth and vasculogenesis. Though our
