Abstract:
We give a construction, for any n 2, of a space S
of spline functions of degree n – 1 with simple knots in (1/4)Z
which is generated by a triple of refinable, orthogonal functions with
compact support. Indeed, the result holds more generally by replacing the
B-spline of degree n – 1 with simple knots at the integers by any
continuous refinable function whose mask is a Hurwitz polynomial of
degree n. A simple construction is also given for the corresponding
wavelets.
