Sylvie Ruette left us on January 2, 2020. She was a lecturer in the Mathematics Department of Orsay and a member of the Topology and Dynamics team. We keep her web page.
I am maître de conférences (associate professor) in
the University Paris-Sud XI.
I am a member of the team of
Topology and Dynamics

My area of research is dynamical systems in discrete time (given by iterating
a map from a space into itself), mainly in dimension 1.
Main topics: maps of topological graphs, interval maps, rotation set, coding,
symbolic dynamics, topological Markov chains, entropy, measures of maximal
Here is a (quite old) summary of my work (a more recent one is available in French).
My Erdös number
is 3 through Bernard Host and Vitaly Bergelson.
This academic year (2019-2020) at the first semester,
I give lectures and tutorials in geometry
in year 0 (transition year between high school and first year studies
for students with a non scientific high school diploma), and
lectures and tutorials in differential equations for third-year students
in biology. At the second semester, I will
givelectures and tutorials in probabiility in year 0, and
tutorials in analysis for first-year students in maths-physics-computer
