|Title:||Measure Rigidity for Random Surface Diffeomorphisms|
|Seminar:||Center for Dynamics and Geometry Seminars|
|Speaker:||Aaron Brown, Penn State|
|We consider stationary and invariant measure for actions by diffeomorphisms on surfaces. Assuming the "fibre entropy" for such an action and measure is non-zero, we deduce the following dichotomy: either the measure is SRB, or the stable distribution is "non-random." We deduce a number of corollaries for actions without common invariant measurable line fields.|
