利用临界理论和S-1指数理论，我们得到了一类二阶时滞微分方程x''(t) = -f(x(t - tau))周期解的存在性和重数性的新结果。 (C) 2008 Elsevier Ltd. 保留所有权利。
By using the critical theory and S-1-index theory, we obtain a new result for the existence and multiplicity of periodic solutions fora class of second-order delay differential equations x ''(t) = -f(x(t - tau)). (C) 2008 Elsevier Ltd. All rights reserved.
