|Title:||Livsic theorem for matrix cocycles|
|Seminar:||Center for Dynamics and Geometry Seminars|
|Speaker:||Misha Guysinsky, PSU|
|I will discuss the recent generalization by B.Kalinin of the Livsic theorem to matrix cocycles over Anosov maps. B.Kalinin proved that if cocycle is alpha-H"older continuous and at periodic points is the Identity map, then it is an alpha-H"older continuous coboundary. I will also discuss an example of two C^infty matrix cocycles that have equivalent matrices at periodic points, but which are not cohomologous over continuous maps.|
