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-

Multiple positive solutions for the system of higher order two-point boundary value problems on time scales

Electronic Journal of Qualitative Theory of Differential Equations, 2009
In this paper, we establish the existence of at least three positive solutions for the system of higher order boundary value problems on time scales by using the well-known Leggett-Williams fixed point theorem.

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

Existence and multiplicity of solutions of fractional differential equations on infinite intervals

Boundary Value Problems
In this research, we investigate the existence and multiplicity of solutions for fractional differential equations on infinite intervals. By using monotone iteration, we identify two solutions, and the multiplicity of solutions is demonstrated by the ...

Three symmetric positive solutions for Lidstone problems by a generalization of the Leggett-Williams theorem

Electronic Journal of Differential Equations, 2000
The authors deal with the existence of three positive solutions to the so-called Lidstone BVP \[ y^{(4)}=f(y,-y''), 0\leq t\leq 1, y(0)=y''(0)=y(1)=y''(1)=0. \] These solutions are required to be symmetric in the sense that they satisfy \(y(t)=y(1-t),\) for all \(t\in[0,1].\) The paper is organized as follows: In section 2 the authors provide some ...
