abstract Riemann surface. As in Theorem 1.2 we show first that f is not constant on any component fl(,~v), l> 0. Hence we can assume using a diagonal process that for a subsequence (fm,),fm,~ h and h = ld on Ut~_of'(~_,p) c {q ~ g2; h(q) = q). Consequently U,~of'(~n) is closed in t2. Since fro, ~ ld on Zn and since f is not of finite order, see [FM], then f is conjugate to an irrational rotation on the Riemann surface E. We then show as in Theorem 2.3 of [FS3] that Z is contained in f2, so E is closed in I2. The rest of the argument is as in Theorem 1.2 or as in [FS3] Theorem 2.3.
