We prove that a metric space is an ANR if, and only if, every open subset of X has the homotopy type of a CW-complex.

Thom polynomials and Schur functions: the singularities $I_{2, 2} (-)$

Similarity:

We give the Thom polynomials for the singularities $I_{2, 2}$ associated with maps $(ℂ^{•}, 0) \to (ℂ^{• + k}, 0)$ with parameter $k \geq 0$ . Our computations combine the characterization of Thom polynomials via the “method of restriction equations” of Rimanyi et al. with the techniques of Schur functions.

Similarity:

For A ⊂ I = [0,1], let $L_{A}$ be the set of continuous real-valued functions on I which vanish on a neighborhood of A. We prove that if A is an analytic subset which is not an $F_{σ}$ and whose closure has an empty interior, then $L_{A}$ is homeomorphic to the space of differentiable functions from I into ℝ.
