### Theme of Workshop:

The workshop will be dedicated to diverse aspects of the algebraic theory of difference equations. We expect to represent topics such as:

- the Galois theory of difference and q-difference equations
- isomonodromic deformation problems and Painlevè differenceequations
- integrability of analytic difference equations
- difference algebraic geometry
- dynamics of rational maps
- connections with the model theory of difference fields

In addition to lectures on research developments, we expect to have a few introductory lectures on some of the topics mentioned above.

### Speakers will include:

G Casale (*Rennes*), Z Chatzidakis (*Paris*), M Gekhtmann (*Notre Dame*), R Halburd (*Univ. College, London*), Ch Hardouin (*Heidelberg*), P Kowalski (*Wroclaw*),
I Laine (*Joensuu*), SP Novikov (*Maryland*), M van der Put (*Groningen*), J-P Ramis (*Toulouse*), J Sauloy (*Toulouse*),
Th Scanlon (*Berkeley*), M Singer (*North Carolina State*), V Sokolov (*Landau Inst., Moscow*), I Taimanov (*Novosibirsk*), H Umemura (*Chuo*), L di Vizio (*Paris*).

### Location:

All lectures will take place in MALL seminar room, on level 8 of the School of Mathematics, University of Leeds.
