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.
