§ 2.. Sp. J. itting~ k _ e~ rod uc t s. When dealing with the ergodic properties of group automorphisms, tronsformations of the following form oftCm arise, l. et U: X-~ X be an invertible measure-preserving transformation (hereafter shortened to" map") of a Lebesque sl~ ace(X,~,), S: G~ G be a (continuuus, algebraic) automorphism of a compact metrizable group C written addi~-i. vely,.~ ntld(~: X-~ G be a measurabl. e luuction. Form the skew product U x S: X x (;-~ X×(; defined i~ y (U x (2'S)(x, I~)=([: x, Sg+.~(x)). Such skew products arise, for example, wilen there is a closed subgroup H of (J that is invarLant under S.['or by taking a Borel cross-section
