Third Tuxedo Day 98/99

Mathematics Institute, University of Warwick (7 June 1999)

The United Kingdom Spatially Extended Dynamics Organisation (TUXEDO) will hold its third meeting for the year at the Mathematics Institute, University of Warwick, on Monday 7 June, from 1-6pm. The programme will be available on when finalised. All are welcome to attend, especially PhD students, and some of the talks will be by PhD students. There is some LMS funding for travel expenses of participants from Surrey, QMW, UCL and Cambridge, and the University of Warwick might be able to contribute to some others' expenses.

Workshop on Skew-Products and Synchronisation of Coupled Systems

University of Surrey (12-13 July 1999)

There will be a workshop to examine the theory of Skew-Product systems and applications to synchronisation and other effects in coupled nonlinear dynamical systems.

Islay, Scotland (19-24 July 1999)

Chris Athorne, Chris Eilbeck, Claire Gilson, Jon Nimmo

A workshop on Integrable Systems: Linear And Nonlinear Dynamics will be held on the Scottish island of Islay (pronounced ``eye-lah'') between the 19th and 24th of July 1999. The main focus of the meeting will be on Darboux transformations, the bilinear method and especially the interplay between them, but contributions in related areas will also be welcome. Because of the limited hotel accommodation on the island, the number of participants is restricted to 50. The workshop will be held at the Machrie Hotel near Port Ellen. All accommodation is at the hotel, some in the hotel building itself and others in self-contained chalets each holding 2 to 4 people. Accommodation for accompanying guests can also be arranged.

Islay has a small airport with flights (Loganair) from Glasgow. Participants may fly directly to Islay on Monday 19th (there are no flights on Sunday) or take a coach and ferry transfer from Glasgow (4--5 hours). The cost will be 280 including 5 nights accommodation and all meals at the hotel, plus 50 registration fee. Some support for UK graduate students is available.

Islay is famous for its range of distinctive malt whiskies from the ''peaty'', such as Laphroaig and Lagavulin, to the lighter tastes of Bruichladdich and Caol Ila, as well as for its secluded and peaceful location. During the course of the workshop participants will have the opportunity to experience the pleasure of both. We hope you will join us in this attractive venue.

If you are interested in attending, please fill in a registration form (available form the organisers) and send or fax it to the address given below, or fill in the same form online at the website. In addition, a (non-refundable) deposit of 75 (pounds sterling) should be paid in order to reserve accommodation in the hotel.
