LARGE-AMPLITUDE SUBHARMONIC OSCILLATIONS FOR SCALAR 2ND-ORDER DIFFERENTIAL-EQUATIONS WITH ASYMMETRIC NONLINEARITIES

[摘要] We provide sufficient conditions for the existence of subharmonic solutions for equations whose nonlinearity may have a different qualitative behaviour to the right and to the left of the origin. The proofs are based on variational methods. (C) 1994 Academic Press, Inc.
