Nonzero solutions of perturbed Hammerstein integral equations with deviated arguments and applications [PDF]

, 2014
We provide a theory to establish the existence of nonzero solutions of perturbed Hammerstein integral equations with deviated arguments, being our main ingredient the theory of fixed point index.

The influence of temperature, humidity and wind on the daily visits to water by the Australian zebra finch

Journal of Avian Biology, Volume 2025, Issue 3, May 2025.
The Australian zebra finch is an arid‐adapted passerine with high hygric demands, that is projected to be at risk from increasing temperature and aridity throughout its distribution by the end of the century. We examine here how individual zebra finches modify their visits to water in response to the climatic conditions of ambient temperature, relative

Positive solutions for Hadamard differential systems with fractional integral conditions on an unbounded domain

Open Mathematics, 2017
In this paper, we investigate the existence of positive solutions for Hadamard type fractional differential system with coupled nonlocal fractional integral boundary conditions on an infinite domain. Our analysis relies on Guo-Krasnoselskii’s and Leggett-
