Özet:

 

In this study, we employ the fixed point theorem of Krasnoselskii andthe concepts of separate and large contractions to show the existenceof a periodic solution of a highly nonlinear delay differential equation.Also, we give a classification theorem providing sufficient conditions foran operator to be a large contraction, and hence, a separate contraction.Finally, under slightly different conditions, we obtain the existence ofa positive periodic solution.
