Let G be the universal cover of the identity component of the contactomorphism group of a lens space. I will discuss the construction of a quasimorphism on G that can be used to detect discriminant points of contactomorphisms. This work is joint with Gustavo Granja, Milena Pabiniak, and Sheila Sandon. Some of its applications for contact rigidity properties of lens spaces are discussed in the lecture by Milena Pabiniak; however, our lectures are independent of each other.
