Elliptic equations with Hardy potentials and gradient-dependent absorption: existence and refined asymptotics

Florica C. Cîrstea, Maria Fărcăşeanu

Under sharp conditions, we prove the existence and refined asymptotic behaviour near zero (resp., at infinity) for all positive radial solutions to elliptic equations such as \begi…

Classification and symmetry of global solutions for nonlinear elliptic equations with mixed reaction terms

Huyuan Chen, Florica C. Cîrstea, Aleksandar Miladinovic

In this paper, we describe the set of all positive distributional $C^{1} (R^{N} ∖ {0})$ -solutions of elliptic equations with mixed reaction terms of the form $$ \mathbb…

Boundedness of solutions to singular anisotropic elliptic equations

Barbara Brandolini, Florica Corina Cirstea

We prove the uniform boundedness of all solutions for a general class of Dirichlet anisotropic elliptic problems of the form $$-Δ_{\overrightarrow{p}}u+Φ_0(u,\nabla u)=Ψ(u,\nabla u…

Sharp existence and classification results for nonlinear elliptic equations in $R^{N} ∖ {0}$ with Hardy potential

Florica C. Cîrstea, Maria Fărcăşeanu

For $N \geq 3$ , by the seminal paper of Brezis and Véron (Arch. Rational Mech. Anal. 75(1):1--6, 1980/81), no positive solutions of $- Δ u + u^{q} = 0$ in $R^{N} ∖ {0}$ exist…

Singular anisotropic elliptic equations with gradient-dependent lower order terms

Barbara Brandolini, Florica C. Cîrstea

We prove the existence of a solution to a singular anisotropic elliptic equation in a bounded open subset $Ω$ of $R^{N}$ with $N \geq 2$ , subject to a homogeneous boundary cond…
