Comparison results for semilinear elliptic equations via Picone-type identities

open access: yesElectronic Journal of Differential Equations, 2009
By means of a Picone's type identity, we prove uniqueness and oscillation of solutions to an elliptic semilinear equation with Dirichlet boundary conditions.

A singular perturbation result for a class of periodic-parabolic BVPs

open access: yesOpen Mathematics
In this article, we obtain a very sharp version of some singular perturbation results going back to Dancer and Hess [Behaviour of a semilinear periodic-parabolic problem when a parameter is small, Lecture Notes in Mathematics, Vol. 1450, Springer-Verlag,

Solutions for autonomous semilinear elliptic equations

open access: yes
We study existence of nontrivial solutions to problem \begin{equation*} \left\lbrace \begin{array}{rcll} -Δu &=& λu+f(u)&\text{ in }Ω,\\ u&=&0&\text{ on }\partial Ω, \end{array}\right. \end{equation*} where $Ω\subset \mathbb{R}^N$ is a smooth bounded domain, $N\geq 1$, $λ\in \mathbb{R}$ and $f:\mathbb{R}\to \mathbb{R}$ is any ...

Note on singular semilinear elliptic equations

open access: yesHiroshima Mathematical Journal, 1992
This note deals with the existence of positive entire solution of the following singular semilinear elliptic equation \[ -\Delta u+c(x)u= p(x)u^{-\gamma}, \quad \text{in } \mathbb{R}^ n, \quad n\geq 3,\quad \gamma>0,\tag{1} \] where \(c\), \(p\) are locally Hölder continuous in \(\mathbb{R}^ n\) with exponent ...

Existence of positive solutions for Dirichlet problems of some singular elliptic equations

open access: yesElectronic Journal of Differential Equations, 2003
When an unbounded domain is inside a slab, existence of a positive solution is proved for the Dirichlet problem of a class of semilinear elliptic equations similar to the singular Emden-Fowler equation.
