DESCRIPTION:Speakers: Pablo Montealegre\n\nThe Farey sequence of order n i
s the ordered sequence of irreducible fractions whose denominator does not
exceed n. Despite this simple definition\, the Farey sequence takes part
in very rich mathematics. Indeed\, consecutive terms in the Farey sequence
satisfy arithmetic and combinatorial relations that make this sequence th
e link between many a priori unrelated topics. This is especially true in
geometry. In this presentation I will illustrate some of the frequent and
elegant appearances of the Farey sequence in geometry\, in particular in h
yperbolic geometry and in flat geometry.\n\nhttps://indico.math.cnrs.fr/ev
