Abstract

Solving R.J. Daverman's problem, V. Krushkal described sticky Cantor sets in RN\mathbb R^N for N4N\geqslant 4; these sets cannot be isotoped off of itself by small ambient isotopies. Using Krushkal sets, we answer a question of J.W. Cannon and S.G. Wayment (1970). Namely, for N4N\geqslant 4 we construct compacta XRNX\subset \mathbb R^N with the following two properties: some sequence {XiRNX, iN}\{ X_i \subset \mathbb R^N \setminus X, \ i\in\mathbb N \} converges homeomorphically to XX, but there is no uncountable family of pairwise disjoint sets YαRNY_\alpha \subset \mathbb R^N each of which is embedded equivalently to XX.
