Abstract:

This paper deals with a new existence theory for positive periodic solutions to  a kind of  nonautonomous Volterra integro differential equations by employing a fixed point theorem in cones. App lying the general theorems established to several biomathematical models, the paper improves some previous results and obt ains some new results.

Key words: Volterra integro differential equation, Existence, Posi tive periodic solution, , Fixed point , theorem
