DESCRIPTION:Speaker: Adi Dickstein\nhosted by Kaloshin Group\nAbstract: Top
 ological quasi-states are special functionals on the algebra of continuous
  functions which are linear on single-generated subalgebras. They trace th
 eir origins to the von Neumann axioms of quantum mechanics. On symplectic 
 surfaces\, every topological quasi-state is symplectic\, i.e.\, linear on 
 Poisson-commutative subalgebras. We discuss the failure of this phenomenon
  in higher dimensions based on the study of symplectic embeddings of polyd
 iscs. Furthermore\, we introduce a Wasserstein-type metric on quasi-states
  and use it for quantitative constraints on symplectic quasi-states. The t
 alk is based on a joint work with Frol Zapolsky.
