Deng, Feiqi; Liu, Yongqing; Jin, Yansheng; Xu, Yumin Stationary oscillations of retarded systems. (Chinese. English summary) Zbl 0927.34051 J. Eng. Math., Xi’an 15, No. 4, 8-12 (1998). Summary: Stationary oscillations of periodic retarded systems are investigated. A necessary and sufficient condition on the existence of stationary oscillations of general retarded systems is given, and a practical result is given for nonperiodic systems. Stationary oscillations of large-scale periodic retarded systems are investigated under weakest conditions on isolated subsystems.
