The Minimal Unitary Representation of E8(8)
Abstract
We give a new construction of the minimal unitary representation of the exceptional group E8(8) on a Hilbert space of complex functions in 29 variables. Due to their manifest covariance with respect to the E7(7) subgroup of E8(8) our formulas are simpler than previous realizations, and thus well suited for applications in superstring and M theory.
