Title: K27 as a symmetry of strings and branes

Abstract:

We will show that the dynamics encoded in the non-linear realisation of the semi-direct product of the very extended Lorentzian Kac-Moody algebra K27 with its vector representation contains the low energy effective action of the closed bosonic string. To set this up, we will review the basic properties of Lorentzian Kac-Moody algebras such as E5, E11, their vector representations, and the method of non-linear realisations.
