摘要：We investigate the existence of periodic solutions of differential systems with a skew-symmetric matrix term and unbounded nonlinearities. Under new generalized Ahmad-Lazer-Paul conditions, some existence results are obtained and some results in the literature are improved. (C) 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
