T (x1'x2'''''Xn) x I x I x I-x I- x I x I}] ere, B denotes the n-dimensional unit cube where a set of measure zero has been removed from such that all iterates of T are well defined. It is well known (see e.~. Schweiqer~ 2!) that T is erqodic with respect to Lebesgue measure I and that T admits a finite invariant measure u, equivalent to I. Since T is er~ odic, u is unique un to a multiplicative constant. If o denotes the density we may write u (E)=; odt E
