XI Encuentro Rioplatense de Álgebra y Geometría Algebraica
15th to 19th December 2003


versión en castellano
In honour of Professor Alfredo Jones
Centro de Matemática
Universidad de la República - Uruguay

Professor A. Jones  worked  for several decades, with dedication and the highest academic quality, at the Mathematics Department of the School  of Sciences. At the occasion of this celebration the Mathematics Department wants  to gather some  of his closest colleagues and  former students.

Presentation 

The Rio de la Plata meetings (ERP) began in 1996.  Alternating between  Montevideo (Uruguay) and Buenos Aires (Argentina) and  with the  participation of mathematicians from the Universidad de Buenos Aires (Argentina) and the Universidad de la República (Uruguay).  Later, mathematicians and students of other Universities e.g. the Universidad Nacional del Sur (Bahía Blanca), the Universidad Nacional de Córdoba (FaMAF) and the Universidad Nacional de Mar del Plata also joined the meetings. 
The talks are generally about research in progress of the participants. Since 2000, there have been also two mini-courses for PhD students. 
 

The main subject of these meetings are:

·   Commutative and Non Commutative Algebra: Quantum Groups, Differential Operator Rings, Hopf Algebras, Lie Theory, Representations of Algebras, etc.;

·   Algebraic Geometry: Algebraic Varieties, Algebraic Groups, Toric Varieties, etc. 


Information about former editions of the meeting can be found in: http://mate.dm.uba.ar/~mfarinat/ERP. 

The XI  meeting will take place in Solís, Uruguay.

    INTERNET

    The hotel is connected to the web, in a connection that is not fast. The cost is less than 2 dollars an hour. At Piriapolis --10 km from the hotel-- there are two
    or three places that sell faster connections. They are open until 23.30 and the cost is about one dollar the hour. The connection speed is also faster than at the hotel.
