Positive periodic solutions for singular fourth-order differential equations with a deviating argument
Published online by Cambridge University Press: 10 May 2018
Abstract
In this paper, we study the singular fourth-order differential equation with a deviating argument:
By using Mawhin's continuation theorem and some analytic techniques, we establish some criteria to guarantee the existence of positive periodic solutions. The significance of this paper is that g has a strong singularity at x = 0 and satisfies a small force condition at x = ∞, which is different from the known ones in the literature.
