Query: Density of States of an Electron in a Gaussian Random Potential for
  (4-epsilon)-dimensional Space   The density of states for the Schroedinger equation with a Gaussian random
potential is calculated in a space of dimension d=4-epsilon in the entire
energy range including the vicinity of a mobility edge. Leading terms in
1/epsilon are taken into account for N \sim 1 (N is an order of perturbation
theory) while all powers of 1/epsilon are essential for N>>1 with calculation
of the expansion coefficients in the leading order in N.
