摘要
本文研究以下一类时间周期反应扩散方程ut=uxxuxf(t,u), x∈R, t>0.的解的长时间渐近行为,其中,f(t,u)是满足双稳型条件且t具有周期性。将通过引入辅助函数,构造适当的上下解,再运用比较原理,可以得到方程解在无穷远处的性质。
This paper focuses on a class of time-periodic reaction-diffusion equationsut=uxxuxf(t,u), x∈R, t>0.of solutions with long time asymptotic behaviour, wheref(t,u)satisfies the bistable condition and t is periodic. The properties of the solutions of the equation at infinity will be obtained by introducing auxiliary functions, constructing appropriate upper and lower solutions, and then applying the comparison principle.
