On fixed points of Knaster continua

Aarts and Fokkink [Proc. Amer. Math. Soc. 126 (1998) 881] have shown that any homeomorphism of the bucket handle has at least two fixed points. Using their methods, we determine the minimum number of fixed points homeomorphisms on generalized one-dimensional Knaster continua can have. We show that there is a class of these continua that admit homeomorphisms with a single fixed point. Among the examples is one that shows that Theorem 15 in [Proc. Amer. Math. Soc. 126 (1998) 881] is incorrect. We also show that there are generalized Knaster continua on which every homeomorphism has either uncountably many fixed points or uncountably many points of period two.
