RésumeThe Grothendieck ring of varieties, introduced in a letter from Alexander Grothendieck to Jean-Pierre Serre (August 16th 1964), plays an important role in algebraic geometry. However, despite the efforts of several mathematicians, the structure of this ring still remains poorly understood. In order to capture some of the flavor of Grothendieck’s ring of varieties, a few motivic measures have been built throughout the years. In this talk I will present a new motivic measure, called the Jacques Tits motivic measure, and describe some of its numerous applications.
