Renormalization and Shearless Invariant Tori: Numerical Results
(272K, plain TeX, two PS figures, data7_7_9.tgz)

ABSTRACT.  We present some numerical evidence for universality 
associated with the breakup of shearless invariant tori, 
by studying a renormalization group transformation 
acting on an appropriate space of Hamiltonians.
