Module and vector space bases for spline spaces
Journal of Approximation Theory, 1991 One way of investigating the dimension of and bases for d-variate polynomial spline spaces \(S^ r_ m(\Delta)\) of given smoothness r and polynomial degree m is to view the union \(S^ r(\Delta)=\cup_{m}S^ r_ m(\Delta)\) as a module over the polynomial ring \({\mathbb{R}}[x_ 1,...,x_ d]\). In this paper, it is shown how in certain cases a module basis of
