KPP 方程是Kolmogorov-Petrovsky-Piskunov 方程的简称。KPP 方程是一个非线性偏微分方程:
![\partial_t u = D \partial^2_x u + a*u+b*u^m](/Images/godic/202502/06/7520d8b112b30c2a02f07e11ed7d20564052.png")
其中a,b,m ≠0,D 为任意常数。

Reaction–diffusion systems are mathematical models which correspond to several physical phenomena: the most common is the change in space and time of the concentration of one or more chemical substances: local chemical reactions in which the substances are transformed into each other, and diffusion which causes the substances to spread out over a surface in space.
