IQI Weekly Seminar

Abstract: I will introduce a formalism based on GNS construction for studying baby universes. By shifting the primordial role to the algebra of observables rather than the Hilbert spaces, I will introduce baby universe operations, build baby universe algebra, and construct the baby universe Hilbert spaces. I will further explain how this approach will give an understanding of the miraculous cancellation as a natural result from the character theory. I will illustrate by giving two different physical settings as examples.
