Abstract: Fusion 2-categories offer a higher dimensional generalization of the category of symmetries in (1+1)d. I will explain how to leverage fusion 2-categories in a special case and apply them to understand the categorical structure of (3+1)d...

Abstract: The James Webb Space Telescope was called the "First Light Machine" when it was being studied as a potential NASA mission.  It quickly became obvious that it would be impossible to prove that the "first" galaxy had been seen, but much more...

Abstract: One of the best understood AdS/CFT incarnations relates tensionless k=1 strings on AdS3 to a symmetric product CFT2. I will discuss an exact duality between string theory on a spacetime which is not asymptotically AdS and a non-conformal...
