For a map , a point is periodic with period if and for all . When is continuous and is an interval, a theorem due to Sharkovskii () states that there is an order in , say , such that if has a periodic point of period and , then also has a periodic point of period . In this work, we will see how an extension of the order to sequences of positive integers yields a Sharkovskii-type result for non-wandering points of .
