Positive periodic solutions and nonlinear eigenvalue problems for functional differential equations
This paper is devoted to investigate the existence of positive periodic solution for a functional differential equation in the form of $\lambda\mathbb{L}x=-b(t)f(x(t-\tau(t))),$ where $\mathbb{L}x=x'(t)-a(t)g(x(t))x(t)$. By using well-known fixed point index theory in a cone, values of $\lambd...
