## Abstract In this paper, we employ a wellβknown fixed point theorem for cones to study the existence of positive periodic solutions to the __n__ βdimensional system __x__ β³ + __A__ (__t__)__x__ = __H__ (__t__)__G__ (__x__). Moreover, the eigenvalue intervals for __x__ β³ + __A__ (__t__)__x__ = __Ξ»
