DESCRIPTION:Maximally supersymmetric string theory compactified on d-dimen
 sional torus is invariant under the non-perturbative U-duality groups E_{d
 +1}(Z).\n\nWe will present the  construction of the automorphic  functions
  relevant for the supersymmetric protected BPS  interactions in the low-en
 ergy expansion of maximal supersymmetric effective action in various dimen
 sions.   We will show that  the support of the non-vanishing Fourier coeff
 icients for these automorphic form is given by the expected BPS conditions
  one can derive from the supersymmetric conditions.\n
