二阶多时滞微分方程周期解的存在性
Existence of Periodic Solutions for Second Order Differential Equations with Multiple Delays
摘要
Abstract
Using the monotone iterative method of upper and lower solutions,we considered the existence of ω-periodic solutions for the second order differential equation with multiple delays -u″(t)=f(t,u(t),u(t-τ1),u(t-τ2),…,u(t-τn)),t ∈ R,where f:R × Rn+1→R was a continuous function which was ω-periodic on t,and τ1,τ2,…,τn were positive constants.By establishing a new maximum principle,we constructed a monotone iterative procedure to seek the ω-periodic solutions of the equation,and proved existence and uniqueness of ω-periodic solutions.关键词
