  • Embeddings into ▫$\mathbb R^m$▫ and the deleted product obstruction
    Malešič, Jože ; Repovš, Dušan, 1954- ; Skopenkov, Arkadij B.
    Let ▫$\tilde{N} = N \times N \setminus (\Delta N)$▫, where ▫$\Delta N$▫ denotes the diagonal. Two counterexamples are constructed: (1) an example of a 3-dimensional manifold ▫$N$▫ with boundary which ... is not embeddable in ▫$\mathbb R^3$▫, but for which there exist an equivariant mapping ▫$\varphi: \sum\tilde{N} \to \sum S^2$▫ and (2) an example of a closed smmoth ▫$4k$▫-dimensional manifold ▫$N$▫ which does not smoothly embed into ▫$\mathbb R^{6k-1}$▫, but for which there exist an equivariant mapping ▫$\tilde{N} \to S^{6k-2}$▫.
