Julian P. Revalski, Professor at the Bulgarian Academy of Sciences, is visiting University of Antilles-Guyane from November 2002 to March 2004 as fellowship of the «Marie Curie» Program of the European Community, contract HPMF-CT-2002-01874. He is jointly invited by the AOC and GRIMAAG research groups.

Among other seminiars, he gave two series of talks:

November 2002-January 2003 :

Les procédures de régularisation pour des opérateurs monotones.

October 2003-March 2004 :

The Banach-Mazur Game: History and Recent Developments.

Notes giving the contents of these two series of seminars have been prepared and are available here:

• Regularisations.pdf
• Banach-Mazur_Game.pdf

(PDF files to be read with Adobe Reader or Ghostview.)
