 Abstract: It has been conjectured that the classical dynamics of M-theory is equivalent to a null geodesic motion in the infinite-dimensional coset space E10/K(E10), where K(E10) is the maximal compact subgroup of the hyperbolic Kac–Moody group E10. We here provide further evidence for this conjecture by showing that the leading higher-order corrections, quartic in the curvature and related 3-form-dependent terms, correspond to negative imaginary roots of E10. The conjecture entails certain predictions for which higher-order corrections are allowed: in particular corrections of type RM(DF)N are compatible with E10 only for M + N = 3k + 1. Furthermore, the leading parts of the R4, R7, ... terms are predicted to be associated with singlets under the decomposition of E10. Although singlets are extremely rare among the 4400 752 653 representations of SL10 appearing in E10 up to level l ≤ 28, there are indeed singlets at levels l = 10 and l = 20 which do match with the R44 and the expected R7 corrections. Our analysis indicates a far more complicated behaviour of the theory near the cosmological singularity than suggested by the standard homogeneous ansätze.
