Jp. Dauer et al., NULL CONTROLLABILITY OF NONLINEAR INFINITE NEUTRAL SYSTEMS WITH DELAYS IN CONTROL, Computers & mathematics with applications (1987), 36(2), 1998, pp. 39-50
The purpose of this paper is to establish sufficient conditions for th
e null controllability of nonlinear infinite neutral systems. Both dis
tributed delays and time varying delays in control variables are discu
ssed. The results are obtained by using the Schauder fixed-point theor
