Título: The Luroth problem and the Cremona group

Ponente: Dr. Arnaud Beauville (Universidad de Nisa)

Lugar: Salón Diego Bricio Hernández

Hora: 16:00 hrs.

Resumen: The Lüroth problem asks whether every subfield of the field of rational functions in  n  variables is itself a field of rational functions.

In geometric terms, if an algebraic variety can be parametrized by rational functions, can one find a one-to-one such parametrization?

After a brief historical survey, I will recall the counter-examples found in the 70's;

then I will describe a quite simple (and new) counter-example.

Finally I'll explain the relation with the study of finite simple groups of birational automorphisms of P^3.
