摘要
研究了中立型Volterra积分微分方程x′(t)=A(t)x(t)+∫t-∞C(t,s)g(s,x(s))ds+∫-t∞B(t,s)x′(s)ds+f(t,x(t))的概周期解的存在性及唯一性问题.利用不动点方法,得到了一些关于该方程的概周期解的存在性及唯一性的新结果.
The problems on the existence and uniqueness of almost periodic solution of the following neutral Volterra integro-differential equationsx'(t)=A(t)z(t)+∫-∞^t C(t,s)g(s,x(s))ds+∫-∞^t B(t,s)x'(s)ds+f(t,x(t)) were dealt with. By using the fixed point method, some new results on the existence and uniqueness of almost periodic solution of the equations were obtained.
