... Now pick any i and let x̃0 ∈ Ui be the unique lift of x0 in Ui . Let S̃n1 be the lift (preimage) of Sn1 in Ui . Let r̃ : Ui → S̃n1 be the retract of S̃n1 ,→ Ui corresponding to r under the homeomorphisms Ui ∼ = U , S̃n1 ∼ = Sn1 . The compact space S̃n1 ∼ = S 1 is closed in X̃ since X̃ is Hausdorff ( ...

... If the points zi are random, then with only mild restrictions on their distribution, ẑ has maximal rank, and so the kernel of ẑ has dimension k. This holds, for example, if the zi are iid with a distribution absolutely continuous with respect to Lebesgue measure. But if we further assume that the ...

... 3. If there is some geometry (i.e. the topology is metrizable) then compactness is equivalent to sequential compactness, which states that for any sequence there is a subsequence that converges. 4. Net convergence: Without geometry, one needs to use more than sequences. A net (xα )α∈I is a collectio ...
