Spectral function for a nonsymmetric differential operator on the half line

Electronic Journal of Differential Equations, 2017
In this article we study the spectral function for a nonsymmetric differential operator on the half line. Two cases of the coefficient matrix are considered, and for each case we prove by Marchenko's method that, to the boundary value problem, there ...

Existence of positive solutions for systems of nonlinear Sturm-Liouville differential equations with weight functions

Electronic Journal of Differential Equations, 2019
This article concerns the existence of component-wise positive solutions for systems of nonlinear Sturm-Liouville differential equations with weight functions, in which one nonlinear term is uniformly superlinear or uniformly sublinear, and the other ...

Positive solutions for singular Sturm-Liouville boundary value problems on the half line

Electronic Journal of Differential Equations, 2010
This article concerns the existence and multiplicity of positive solutions for the singular Sturm-Liouville boundary value problem $$displaylines{ (p(t)u'(t))'+h(t)f(t,u(t))=0,quad 0<t<infty,cr au(0)-blim_{to 0^+}p(t)u'(t)=0,cr clim_{to infty}
