Spacelike Singularities and Hidden Symmetries of Gravity (2008)
Henneaux Marc, Persson Daniel, Spindel Philippe
We review the intimate connection between (super-)gravity close to a spacelike singularity (the âBKL-limitâ) and the theory of Lorentzian Kac-Moody algebras. We show that in this limit the...
