Pulsating wave has a property of recurrence up to certain time and space shifts. It has been intensively studied for reaction-diffusion equations in time or space periodic media, but it may not exist in time-space periodic media. In this talk, for a class of evolution systems admitting the comparison principle, we construct a kind of generalized transition wave that was introduced by H. Berestycki and F. Hamel in 2012. It turns out that the constructed transition wave has a property of almost recurrence.
