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 is monostabl…

Precise propagation profile for some monostable free boundary problems in time-periodic media
Yihong Du, Zhuo Ma, Zhi-Cheng Wang
We consider reaction-diffusion equations of the form \begin{equation*} u_t - d u_{xx} = f(t,u), \quad t>0,\ \ x \in [g(t), h(t)], \end{equation*} where is periodic in …
