Explore the construction of Gibbs measures as invariant measures for geodesic flows on hyperbolic surfaces in this advanced mathematics lecture. Learn about the thermodynamical formalism approach to creating these "good" invariant measures and discover their crucial ergodic properties. Examine how these Gibbs measures serve as powerful tools for solving geometric problems, including analyzing the regularity of entropy under metric changes and investigating horocyclic flows on abelian covers of compact hyperbolic surfaces. Delve into the intersection of dynamical systems, differential geometry, and statistical mechanics through rigorous mathematical exposition suitable for researchers and advanced graduate students in mathematics.
