Abstract: In recent years operator systems --- unital self-adjoint spaces of operators --- have come to be seen as "quantum" graphs. The original motivation for this analogy came from quantum error correction, but the subject has developed a life of its own. I will discuss quantum Ramsey theory, the quantum Turan problem, and quantum chromatic number.

I will mostly stick to the finite dimensional setting, so there will be few prerequisites beyond linear algebra over the complex numbers.

Noncommutative Geometry in NYC

Series comments: Noncommutative Geometry studies an interplay between spatial forms and algebras with non-commutative multiplication. Our seminar welcomes talks in Number Theory, Geometric Topology and Representation Theory linked to the context of Operator Algebras. All talks are kept at the entry-level accessible to the graduate students and non-experts in the field. To join us click sju.webex.com/meet/nikolaei (5 min in advance) and igor DOT v DOT nikolaev AT gmail DOT com to subscribe/unsubscribe for the mailing list, to propose a talk or to suggest a speaker. Pending speaker's consent, we record and publish all talks at the hyperlink "video" on speaker's profile at the "Past talks" section. The slides can be posted by providing the organizers with a link in the format "myschool.edu/~myfolder/myslides.pdf". The duration of talks is 1 hour plus or minus 10 minutes.
