Dynamics & probability: Lucia Simonelli - Absolutely Continuous Spectrum for Parabolic Flows/Maps

Tue, 06/12/201614:00-15:00
Manchester building, Hebrew University of Jerusalem, (Room 209)
This talk will discuss some recent developments in the study of the spectral
properties of parabolic flows and maps. More specifically, it will focus on
the techniques used to determine the spectrum of the time-changes of the
horocycle flow and and the effort to generalize these methods to create conditions
under which a general parabolic flow/map would be expected to have absolutely continuous
