Three positive solutions for second-order periodic boundary value problems with sign-changing weight
Abstract In this paper, we study the global structure of positive solutions of periodic boundary value problems {−u″(t)+q(t)u(t)=λh(t)f(u(t)),t∈(0,2π),u(0)=u(2π),u′(0)=u′(2π), $$\textstyle\begin{cases} -u''(t)+q(t)u(t)=\lambda h(t)f(u(t)), \quad t\in (0,2\pi ), \\ u(0)=u(2\pi ), \quad\quad...
