DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NYC-NCG/117/
 ">Categories of Hilbert spaces</a>\nby Andre Kornell (Dalhousie University
 ) as part of Noncommutative geometry in NYC\n\n\nAbstract\nHilbert spaces 
 form one category with bounded operators and another category with contrac
 tions. I will present axioms for each of these two categories. These axiom
 s are interesting because they make no explicit reference to the real numb
 er system. The proof appeals to Soler's theorem and to the theory of dagge
 r categories\, as well as to a few familiar results from operator theory.\
