Abstract:
This article concerns the positive periodic solutions for a system
of second-order nonlinear ordinary differential equations,
in which the nonlinear term is sublinear in one equation and superlinear
in the other equation.
By using the fixed point theorem of cone expansion and compression
we obtain the existence of positive periodic solutions.
