The illumination problem

The following elementary problem in geometry is still open: given a polygon in the plane, say that points and in see each other if there is a billiard path from to . Is there a polygon in which infinitely many pairs of points do not see each other?

Such problems turn out to be easy to state but very difficult to solve. I will explain this and related questions in greater detail, and describe some recent progress which relies on well-known work of Eskin and Mirzakhani (part of the late Maryam Mirzakhani’s Field medal citation).
