Trichotomy dynamics of a free boundary model for biological invasion

Hongkai Cao, Yihong Du, Wenjie Ni +1

It is well known that the reaction-diffusion equation $u_{t} = d u_{xx} + f (u)$ with compactly supported nonnegative initial functions exhibits trichotomy dynamics for bistable and combus…

Semi-wave and sharp estimates of propagation for monostable free boundary problems in time-periodic environment

Yihong Du, Zhuo Ma

We investigate the propagation profile of positive solutions to \begin{equation*} u_t-du_{xx}=f(t,u) \mbox{ for } t>0,\ x\in(g(t),h(t)), \end{equation*} where $f (t, u)$ is monostabl…
