Abstract

The aim of this errata is to claim that [2, Theorem 4.5] is not true. This mistake was pointed to us by W. J. Charatonik. In the false "proof" of [2, Theorem 4.5] the authors argue by a false note mentioned by Bing that every continuum which is both arc-like and circle-like is indecomposable [1, p. 121]. A counterexample to Bing's note as well as to [2, Theorem 4.5] is given by two bucket-handle continua joined by their end-points. Another counterexample is described in [3, Examples].
