Algebraic Dynamics Seminar at Harvard
We meet in Room 232 of the Science Center, usually on Thursdays at 4pm. Seminars are typically two hours long, with a break in the middle and the second hour for more details. Please email me (Laura DeMarco) if you are interested in joining the email list, so I can send you announcements. The math department is locked, so you should contact me if you are not from Harvard but would like to attend a lecture.
See also the Informal Geometry & Dynamics seminar on Wednesdays.

Title: Generalized u-Gibbs Measures for $C^\infty$ Diffeomorphisms
Abstract: We show that for every $C^\infty$ diffeomorphism of a closed Riemannian manifold, if there exists a positive volume set of points with a positive Lyapunov exponent (in a weak sense) then there exists an invariant probability measure with a disintegration by absolutely continuous conditionals on disks subordinated to unstable leaves. As an application, we prove a strong version of the Viana conjecture in any dimension. This is joint work with D. Burguet.
