Abstract: Existence of periodic solutions to second order differential systems with gyroscopic forces is considered via variational methods, where a generalized Ahmad-Lazer-Paul type condition is used. We do not impose the condition that the gyroscopic forces are small. (C) 2011 Elsevier Ltd. All rights reserved.
