A coset model based on the hyperbolic Kac–Moody algebra E10 has been conjectured to underly eleven-dimensional supergravity and M theory. In this note we study the canonical structure of the bosonic model for finite- and infinite-dimensional groups. In the case of finite-dimensional groups like GL(n) we exhibit a convenient set of variables with Borel-type canonical brackets. The generalisation to the Kac–Moody case requires a proper treatment of the imaginary roots that remains elusive. As a… 
Higher spin representations of K(E10)
We review the recently constructed non-trivial fermionic representations of the infinite-dimensional subalgebra K(E10) of the hyperbolic Kac--Moody algebra E10. These representations are all

Duality symmetries in supergravity : New structures and deformations
Maximal supergravity theories in 2 < D < 10 dimensions are known to possess intriguing global symmetries, known as duality symmetries, which can be optionally broken by turning on non-abelian gauge
Standard Model Fermions and Infinite-Dimensional R Symmetries.
TLDR
This proposal relies in an essential way on embedding the SU(8) R symmetry of N=8 supergravity into the (infinite-dimensional) "maximal compact" subgroup K(E_{10}) of the conjectured maximal duality symmetry E_{10}.
