Theory Seminar

KEK Theory Seminar (Dr. Marcus Sperling)

Start:2017/10/31 (Tue) 11:00 AM
End:2017/10/31 (Tue) 12:00 PM
Location:Kenkyu-Honkan 1F, Meeting Room 1

Speaker:Dr. Marcus Sperling ( University of Vienna )
Contact:Covariant fuzzy spaces, matrix models and higher spin


In this talk, I will discuss the generalised and basic fuzzy 4-sphere in the context of the IKKT matrix model. These spaces arise as SO(5)-equivariant projections of quantised SO(6) coadjoint orbits and exhibit full SO(5) covariance. I will sketch how (basic and generalised) 4-sphere arise as solutions in a Yang-Mills matrix model, such that the fluctuations on the 4-sphere lead to a higher-spin gauge theory.
