Rigidity and Uniform Rigidity
Abstract: In this talk we will discuss rigidity sequences and uniform rigidity sequences. I will give examples of each for weakly mixing transformations and inform you of what has been done thus far to characterize the structure of these sequences. Then I will discuss a generic result regarding weakly mixing homeomorphisms of the two torus that are uniformly rigid and show that if a sequence satisfies a certain growth rate then there is a weakly mixing homeomorphism of the two torus that is uniformly rigid with respect to the given sequence.
