Main Topics

Priority at the Conference will be given to those subjects most closely related to the spirit of Alfred Gray's work: special Riemannian manifolds, homogeneous spaces, complex structures, symplectic manifolds, geometry of geodesic spheres and tubes and related problems, geometry of surfaces, computer graphics in differential geometry and Mathematica ®.

Programme

• The afternoon of Wednesday 20 will be free. We are organising a tour of the main sightseeing spots in Bilbao and the surroundings areas.
  

• Round Table discussion On the morning of Saturday 23 we will be staging a round table discussion, with the participation of J. P. Bourguignon (chairman), S. Donaldson, J. Eells, M. Gromov and S. Novikov.
  

• To follow this we are trying to arrange a concert of classical music. We also plan to organise a visit after lunch to the Guggenheim Museum.

List of participants

The following people have already expressed an explicit interest in attending the Congress. The current list of possible participants are available on the Word Wide Web

Submission of abstracts

For submission of abstracts we have decided to use facilities of Atlas Mathematical Conference Abstracts. If you wish to present an oral communication or a poster, please submit before May 31, 2000, an extended (up to two pages) abstract (either plain ASCII or TeX) via

If the Organizing Committee accept your oral communication or your poster, your abstract will become avaible to every-one via

We plan the publication of the Proceedings of the Congress.

Conference fee

The participation fee is 15.000 pesetas (90 Euros or 100 USD) if you pay it before April 30, 2000. After this date, the participation fee is 20.000 pesetas (120 Euros or 140 USD).

For students, the reduced participation fee is 10.000 pesetas (60 Euros or 70 USD).

It should be paid by a Transfer Bank to Bilbao Bizkaia Kutxa

Support

We hope to be able to support participants from countries in a difficult economic situation and young mathematicians.

IBERIA will be the official carrier for the Congress, and has offered the following special terms:

For Congress participants:

25 % discount on full rate (Business & Tourist class) for domestic, European and intercontinental flights with final destination Bilbao and return. On European flights the PEX fare, and on intercontinental flights the Excursion rate, may be applied without conditions, subject to availability of seats. This offer applies only to closed tickets with IBERIA issued by Iberia ticket offices or the Official Travel Agency:

Tickets will be valid from two days before to two days after the congress dates.

For the Organizing Committee and guest speakers:

30 % discount on full rate (Business & Tourist class) for domestic, European and intercontinental flights with final destination Bilbao and return. On European flights the PEX fare, and on intercontinental flights the Excursion rate, may be applied without conditions, subject to availability of seats. This tickets must be purchased from Iberia offices.

Up to 8 pre-congress tickets on these terms may be purchased from Iberia ticket offices by the Organizing Committee on the International Congress on Differential Geometry.

Passengers wishing to take up these offers must prove their participation in the congress. All the Iberia tickets issued for this Congress must bear an ID code. Participants who need this code can obtain it from the Official Travel Agency or the Organizing Committee.

Lodging

The Meeting will take place in the buildings of Facultad de Ciencias Económicas y Empresariales (Avenida Lehendakari Agirre 83, Bilbao). We suggest that all participants stay in nearby Colegio Mayor Miguel de Unamuno (Avenida Lehendakari Agirre 140). The lunch and supper for all participants will be served in Colegio Mayor Miguel de Unamuno.

Please, for the lodging, contact:

If you want to share a room with somebody in Colegio Mayor Miguel de Unamuno, please indicate this to the Travel Agency VIAJES ECUADOR. And if we have arranged yet to share a room with somebody participating in the Congress, give this person's name to the Travel Agency.

WARNING!!

Participants are advised that there will be several congresses and trade fairs at around the same date, so arrangements should not be left until the last minute.
