Outer compositions of hyperbolic/loxodromic linear fractional transfomationsDOI: 10.1155/s016117129200108x Keywords: linear fractional transformations , continued fractions , fixed points. Abstract: It is shown, using classical means, that the outer composition of hyperbolic or loxodromic linear fractional transformations {fn}, where fn ¢ ’f, converges to ±, the attracting fixed point of f, for all complex numbers z, with one possible exception, z0. I.e.,Fn(z):=fn ¢ fn ¢ ’1 ¢ ¢ € | ¢ f1(z) ¢ ’ ±When z0 exists, Fn(z0) ¢ ’ 2, the repelling fixed point of f. Applications include the analytic theory of reverse continued fractions.
