Various characterisations of Extended Chebyshev spaces via blossoms
[Quelques caractérisations des espaces de Chebyshev généralisés liées à la notion de floraison.]
Comptes Rendus. Mathématique, Tome 339 (2004) no. 11, pp. 815-820.

Parmi les W-espaces (espaces à Wronskiens sans zéro), les espaces de Chebyshev généralisés se caractérisent par l'existence de bases de Bernstein, ou de points de Bézier, ou de floraisons, ou de bases de B-splines, dans l'espace obtenu par intégration.

Among all W-spaces (i.e. spaces with nonvanishing Wronskians), extended Cheyshev spaces can be characterised by the existence of either Bernstein bases, or B-spline bases, or Bézier points, or blossoms in the spaces obtained by integration.
