Abstract

Three term recurrence relations yn+1 +bnyn +anyn?1 = 0 can be

on the asymptotic nature of the function to be computed, different recursion

for dominant solutions. However, some solutions interchange their role for

solutions may transitorily behave as minimal. This phenomenon, related

confluent hypergeometric functions, is shown to be a general situation which

analyze the anomalous convergence of the associated continued fractions for

and Gauss hypergeometric functions) and discuss the implication of such

transitory behaviour on the numerical stability of recursion.
