Discrete Integrable Systems
Sakai’s elliptic Painlev equation is constructed via the geometry of certain rational algebraic surfaces. I’ll discuss joint work with Arinkin and Borodin in which we interpret Sakai’s surfaces as moduli spaces of secondorder linear elliptic difference equations (and related objects), such that the elliptic Painlev equation itself acts via isomonodromy transformations. The construction also lends itself to higherorder problems, and/or problems with more complicated singularity structure; I’ll discuss what is known about the corresponding higherdimensional moduli spaces.
