Event description:
For traditional horocycle flow in SL(2, R), the detailed analysis of the cohomological equation Uf=g was given by Flaminio-Forni. Their result was further applied in some rank-one models to obtain cocycle rigidity for higher rank parobolic actions. In this talk I will discuss a general result about cocycle rigidity of parabolic actions and will show how to use representation tool in higher rank Lie groups.
