It is well known that integrable PDEs such as the KdV equation can be reduced to the Painlevé equations via similarity reductions. Moreover, the search for a discrete analogue of similarity reduction, called a periodic reduction from a partial difference equation to a discrete Painleve equation, has been a very active research area.
In this talk, we show how to obtain discrete Painlevé equations from a periodic reduction of a system of partial difference equations on the 4-dimensional integer lattice.
