This paper deals with Vandermonde matrices on Chebyshev points, hereafter denoted by V. We present simple formulas for the determinant of I" and the Frobenius norm of both V and V -~, and derive an algorithm for solving the linear systems l/'p =f and VTq = g.

Extending a result recently obtained for Chebyshevian splines, we give a necessary and sufficient condition for the existence of blossoms (or, equivalently, of B-spline bases) for splines with connection matrices and with sections in different four-dimensional quasi-Chebyshev spaces. We apply this r
