    摘要: 這篇文章中,我們探討離散型反應擴散方程u_t(x,t)=u(x+1,t)-2u(x,t)+u(x-1,t)+f(u(x,t)),其中
    反應項f(u)=u^2(1-u)。在此,
    我們證明此方程式存在一種全解其動態行為宛如兩個來自x軸兩端相向而行的行波。
    This paper deals with a discrete reaction-diffusion equation
    u_t(x,t)=u(x+1,t)-2u(x,t)+u(x-1,t)+f(u(x,t)),
    where f(u)=u^2(1-u). Here, we prove there exist entire solutions which behave as two
    traveling waves coming from both sides of x-axis.
