Title: "A survey of results and open problems on the Schilling equation"

Abstract: The Schilling equation is the functional equation

4q f(qx) = f(x-1) + f(x+1) + 2f(x)

for real x with a parameter q in (0,1).

It has its origin in Physics, and although it has been studied intensively in recent years, there are still many open questions connected with it. Some questions, however, have been answered recently. In the talk, we will survey known results about Schilling's equation and point out problems which are still open.
