Workshop NLAGA-UCAD-2014


Hyperbolic Geometry : Counting, Rigidity.


  • Place: University Cheikh Anta Diop of Dakar, Senegal

  • Dates: October from the 10th to the 18th, 2014.

  • Coordonnateur: Massèye Gaye (University Cheikh Anta Diop of Dakar)

  • Description: This workshop entitled Counting, rigidity, is  a part of the NLAGA Project. Actually it is related to the Task 10, in collaboration with the Laboratory of Geometry and Applications of university Cheikh Anta Diop of Dakar. The two invited lecturers  were Barbara Schapira, Associate professor  at the University of Jule Verne of Amiens (France) and Gilles Courtois, Research Director of CNRS at the University Pierre et Marie Curie of Paris, in France. Two courses were offered during the week. The first one "Counting of orbits" has been done by Dr Barbara Schapira and the second one "Mostow's Rigidity by DR. Giles Gourtois.

    As an outcome of this workshop, three students have taken the subjects  to do master theses linked to these courses in order to do PhD thèses in this area.

    Course I :
    Chapter 1 : Introduction to hyperbolic geometry
    Chapter 2 : Notions on  the Counting and strategies
    Chapter 3 : Construction in the sensé of Patterson-Sullivan and properties

    Course II :
    Chapter 1 : Hyperbolic surface
    Chapter 2 : Mostow’s Theorem
