"A Proper Separation -- The Variety Show"

Well, it has only taken two years, but we are finally ready to give the scheme-theoretic definition of "variety". Along the way, we discuss the notions algebraic geometers use in place of "Hausdorff" and "compact Hausdorff", namely "separated" and "proper" morphisms. Somehow, it seems fitting to talk about "separation" as we bring this seminar to a close...

"Existence of the C*-envelope"

In 1969, Arveson defined the C*-envelope of an operator algebra or operator system as a universal quotient amongst all C*-algebras which contain it. He left the existence of the C*-envelope as an open problem. In a whirlwind tour of my Master's research paper, I'll discuss the diverse tools used to prove its existence in the intervening decades.
