Lindeberg-Feller theorems on Lie groups

Necessary and sufficient conditions are given for a triangular array of probability measures on an arbitrary Lie group to converge to a Gauss measure. The main step of the proofs is an estimation for the Fourier transform of a probability measure in terms of integrals of local coordinates and a Hunt function, suggested by Professor E. Siebert. The special case of stratified nilpotent Lie groups is investigated separately.
