摘要 研究神经网络中的一个积分微分方程:ut=f(u,w)+α∫RK(x,y)H(u(y,t)-θ)dy行波解的存在唯一性问题.进行参数配置,使用Matlab软件绘制出了一个具有六个不动点的相位图,在数值模拟角度说明了已有的存在唯一性定理不成立. The traveling wave solution of an integral differential equation arising from neuronal networks is discussed.By choosing certain group of parameters and using Matlab software,the portrait in phase-plane is obtained.It shows that the traveling wave solution assumed does not exist.
