Existence of radial positive solutions vanishing at infinity for asymptotically homogeneous systems

open access: greenElectronic Journal of Differential Equations, 2010
In this article we study elliptic systems called asymptotically homogeneous because their nonlinearities may not have polynomial growth. Using the Gidas-Spruck Blow-up method, we obtain a priori estimates, and then using Leray-Schauder topological ...

Bifurcation along curves for the p-Laplacian with radial symmetry

open access: yesElectronic Journal of Differential Equations, 2012
We study the global structure of the set of radial solutions of a nonlinear Dirichlet eigenvalue problem involving the p-Laplacian with p>2, in the unit ball of $mathbb{R}^N$, $N geq 1$.

Radial positive solutions for (p(x),q(x))-Laplacian systems

open access: yesBoletim da Sociedade Paranaense de Matemática, 2022
In this paper, we study the existence of radial positive solutions for nonvariational elliptic systems involving the p(x)-Laplacian operator, we show the existence of solutions using Leray-Schauder topological degree theory, sustained by Gidas-Spruck Blow-up technique.

Positive radial solutions for a class of quasilinear Schrödinger equations in $\mathbb{R}^3$

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2022
This paper is concerned with the following quasilinear Schrödinger equations of the form: \begin{equation*} -\Delta u-u\Delta (u^2)+u=|u|^{p-2}u, \qquad x\in \mathbb{R}^3, \end{equation*} where $p\in\left(2,12\right)$.

Multiple positive solutions to elliptic boundary blow-up problems [PDF]

open access: yes, 2016
We prove the existence of multiple positive radial solutions to the sign-indefinite elliptic boundary blow-up problem \[ \left\{\begin{array}{ll} \Delta u + \bigl(a^+(\vert x \vert) - \mu a^-(\vert x \vert)\bigr) g(u) = 0, & \; \vert x \vert < 1, \\ u(x)
