Abstract

This paper proposes a method of expansion for automorphic functions on Lie groups, which generalizes the usual Fourier series expansion of automorphic functions on SL2(ℝ)/SO(2). Detailed consideration is given to the special case of the expansion of functions on SL3(ℝ)/SO(3), which are automorphic with respect to SL3(ℤ).
