On the Solution of the Dirichlet Problem for Second-Order Elliptic Systems in the Unit Disk

open access: yesMathematics, 2023
The role played by explicit formulas for solving boundary value problems for elliptic equations and systems is well known. In this paper, explicit formulas for a general solution of the Dirichlet problem for second-order elliptic systems in the unit disk

Uniqueness theorem for partially observed elliptic systems and application to asymptotic synchronization

open access: yesComptes Rendus. Mathématique, 2020

The p-ellipticity condition for second order elliptic systems and applications to the Lamé and homogenization problems

open access: yesJournal of Differential Equations, 2021
The notion of $p$-ellipticity has recently played a significant role in improving our understanding of issues of solvability of boundary value problems for scalar complex valued elliptic PDEs. In particular, the presence of $p$-ellipticity ensures higher regularity of solutions of such equations.

On nonnegative radial entire solutions of second order quasilinear elliptic systems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2002
In this article we consider the second order quasilinear elliptic system of the form $$\Delta_{p_i} u_i=H_i(|x|)u_{i+1}^{\alpha_i}, x\in \mathbb{R}^N, i=1,2,...,m$$ with nonnegative continuous function $H_i$.

NONTRIVIAL RADIAL SOLUTIONS FOR A SYSTEM OF SECOND ORDER ELLIPTIC EQUATIONS

open access: yesJournal of Applied Analysis & Computation, 2022
Summary: In this paper we use the topological degree and the Krein-Rutman theorem to investigate the existence of nontrivial radial solutions for a system of second order elliptic equations. Our results are obtained under some conditions involving the eigenvalues of a relevant linear operator.
