In [2] and [3], W.M. Boyce and J.P. Huneke answered this question independently by the construction of a pair of commuting continuous functions which have no fixed point in common. This conjecture led us to introduce the common periodic point conjecture (see [1]) which reads as: Conjecture. If f and g are continuous functions from [0, 1] to itself which commute (i.e. f(g(x)) = g(f(x))), then they must have a common periodic point. In fact we conjectured that typically commuting continuous self-maps of closed intervals do not share a periodic point. In this talk we give the history of this conjecture as well as some related results and some open questions.enCC0 1.0 Universalinfo:eu-repo/semantics/openAccessConference Object8988
