Abstract

Periodic solutions for differential equations at resonance with unbounded nonlinearities were discussed. Nonlinear system of first-order functional differential equations of mixed type was considered. Results showed sufficient conditions for the existence of periodic solutions of nonlinear coupled differential systems and Duffing equations at resonance with unbounded nonlinearities.
