Abstract

Let C\mathcal C be the Cantor set. For each n3n\geqslant 3 we construct an embedding A:C×CRnA: \mathcal C \times \mathcal C \to \mathbb R^n such that A(C×{s})A(\mathcal C \times \{s\}), for sCs\in\mathcal C, are pairwise ambiently incomparable everywhere wild Cantor sets (generalized Antoine's necklaces). This serves as a base for another new result proved in this paper: for each n3n\geqslant 3 and any non-empty perfect compact set XX which is embeddable in Rn1\mathbb R^{n-1}, we describe an embedding A:X×CRn\mathbb A : X \times \mathcal C \to \mathbb R^n such that each A(X×{s})\mathbb A (X \times \mathcal \{s\} ), sCs\in \mathcal C, contains the corresponding A(C×{s})A (\mathcal C \times \{s\} ), and is ``nice'' on the complement A(X×{s})A(C×{s})\mathbb A (X \times \mathcal \{s\} )-A (\mathcal C \times \{s\} ); in particular, the images A(X×{s})\mathbb A ( X \times \{s\}), for sCs\in\mathcal C, are ambiently incomparable pairwise disjoint copies of XX. This generalizes and strengthens theorems of J.R.Stallings (1960), R.B.Sher (1968), and B.L.Brechner-J.C.Mayer (1988).
