Nicolas Bergeron (19 December 1975 – 15 February 2024) was a French mathematician who worked in Pierre and Marie Curie University in Paris.

Early career

Bergeron obtained his PhD at École normale supérieure de Lyon in the year 2000 under the supervision of Jean-Pierre Otal. His thesis was titled Cycles géodésiques dans les variétés hyperboliques ("geodesic cycles in hyperbolic varieties").[1]

Work

Bergeron's main interests concerned the geometry and topology of locally symmetric spaces and arithmetic groups, as well as their cohomology,[2] and their connection to number theory, in particular to Hilbert's 12th problem.[3][4]

Some of his publications showed an interest in Oulipo, referencing An Attempt at Exhausting a Place in Paris by Georges Perec.[5] He also wrote a (non-mathematical) article about Jacques Roubaud.[6]

Bergeron was latterly a member of the editorial board of the journal Publications Mathématiques de l'IHÉS.[7]

Death

Bergeron died on 15 February 2024, at the age of 48.[8]
