Explore a mathematical seminar lecture examining C0-rigidity and flexibility phenomena in contact transformations, with a focus on how contact squeezing and non-squeezing dichotomy manifests in contact homeomorphisms groups. Delve into the definition of a novel conjugation-invariant norm on smooth contactomorphisms groups and its relationship to contact fragmentation norm. Learn about the C0-local boundedness of Sandons spectral norm through this presentation by Vukašin Stojisavljević from the Centre de recherches mathématiques at the University of Montreal. Based on joint research with Baptiste Serraille, this Symplectic Geometry Seminar presentation offers insights into the mathematical study of contact transformations and their associated group properties.
