Title: Jacques Tits motivic measure
Abstract: The 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, which will be accessible to a wide audience, I will present a new motivic measure, called the Jacques Tits motivic measure, and describe some of its numerous applications.
Gonçalo Tabuada (University of Warwick, UK and Nova University, Portugal)
Portuguese mathematician working at the University of Warwick, UK, and at the Universidade Nova de Lisboa, Portugal. He studied at École Polytechnique in France, wrote a PhD thesis at Université Paris VII under the supervision of Bernhard Keller, and subsequently worked for one decade at the Massachusetts Institute of Technology (MIT). His research is mainly focused on algebraic topology, noncommutative algebraic geometry, K-theory, motives, and homological/homotopical algebra. He published more than 80 articles as well as one book entitled “Noncommutative Motives”. In 2014 he was awarded the NSF CAREER Award, which is the highest award bestowed by the United States government on outstanding scientists and engineers in the early stages of their independent research careers. In 2020 was elected a member of the Portuguese Academy of Sciences.
