Sur un exemple de Banach et Kuratowski

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.

Thom polynomials and Schur functions: the singularities I 2 , 2 ( - )

Piotr Pragacz (2007)

Annales de l’institut Fourier

Similarity:

We give the Thom polynomials for the singularities I 2 , 2 associated with maps ( , 0 ) ( + k , 0 ) with parameter k 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.
