Abstract
This paper treats the embedding of finite-dimensional subsets of a Banach space B into finite-dimensional Euclidean spaces. When the Hausdorff dimension of X-X is finite, d(H)(X-X) < k, a prevalent set of linear maps from B into R-k are injective on X. The proof motivates the definition of the 'dual thickness exponent', which is the key to proving that a prevalent set of such linear maps have Holder continuous inverse when the box-counting dimension of X is finite and k > 2d(B)(X). A related argument shows that if the Assouad dimension of X-X is finite and k > d(A)(X-X), a prevalent set of such maps are bi-Lipschitz with logarithmic corrections. This provides a new result for compact homogeneous metric spaces via the Kuratowksi embedding of (X, d) into L-infinity(X).
