"The topological pressure as a dynamical 'generating function'"

** Abstract: **

Ruelle and Walters had associated for suitable dynamical
systems T:X-->X a certain convex functional called the
topological pressure. Much like the free energy of
statistical physics, the topological pressure functional
encodes dynamical and statistical information on the system
through the behavior of its directional derivatives and
their singularities. I will describe some of this
information, with particular emphasis on the meaning of the
singularities ("dynamical phase transitions").

Light refreshments will
be served in the faculty lounge at 3:30.
