Limiting behavior of principal eigenvalues for a class of mixed boundary value problems as the measure of the support domain goes to zero
J. Lopez-Gomez, A. Sahuquillo
In this paper we characterize the limiting behavior of the principal eigenvalue, $\s_1[-\D,\b,Ã]$, of the boundary value problem \eqref{1.1} as the Lebesgue measure of the underly…

Large positive solutions for a class of 1-D diffusive logistic problems with general boundary conditions
Julián López-Gómez, Alejandro Sahuquillo, Andrea Tellini
The first goal of this paper is to establish the existence of a positive solution for the singular boundary value problem (1.1), where is a general boundary operator…
