Differential Equations & Applications, 2020 In Theorem 3 of [2] I included an extension to the Ascoli theorem. While the statement of the theorem and its later use were correct, the proof has a slight error which I noticed while in the process of writing a sequel.

Nonlinear Eigenvalues and Bifurcation Problems for Pucci's Operator [PDF]
, 2004 In this paper we extend existing results concerning generalized eigenvalues of Pucci's extremal operators. In the radial case, we also give a complete description of their spectrum, together with an equivalent of Rabinowitz's Global Bifurcation Theorem ...

New results for the Liebau phenomenon via fixed point index
, 2016 We prove new results regarding the existence of positive solutions for a nonlinear periodic boundary value problem related to the Liebau phenomenon. As a consequence we obtain new sufficient conditions for the existence of a pump in a simple model.

Positive solutions for a fourth-order p-Laplacian boundary value problem with impulsive effects
Boundary Value Problems, 2013 This paper is devoted to study the existence and multiplicity of positive solutions for the fourth-order p-Laplacian boundary value problem involving impulsive effects {(|y″|p−1y″)″=f(t,y),t∈J,t≠tk,Δy′|t=tk=−Ik(y(tk)),k=1,2,…,m,y(0)=y(1)=y″(0)=y″(1)=0 ...

Positive solutions for a class of superlinear semipositone systems on exterior domains
, 2014 We study the existence of a positive radial solution to the nonlinear eigenvalue problem −Δu=λK1(|x|)f(v) in Ωe, −Δv=λK2(|x|)g(u) in Ωe, u(x)=v(x)=0 if |x|=r0 (>0), u(x)→0, v(x)→0 as |x|→∞, where λ>0 is a parameter, Δu=div(∇u) is the Laplace operator, Ωe=
