一类Duffing型微分方程2π周期解的存在唯一性

On existence and uniqueness of 2π-periodic solution for a Class of Dufffing Equations

研究了Duffing型微分方程a¨x +c x(t) +bx(t) +g(x(t-τ) ) =p(t) ,得到了其存在唯一周期解充分条件 .

Is this paper,a 2π- periodic solution on Duffing equation a+c(t)+bx(t)+g(x(t-τ))=p(t) are studied, a sufficient condition for the existence and uniqueness of 2π- periodic solutions are obtained.
