On multivariate E-splines. (English) Zbl 0706.41010

The paper settles some of the open problems suggested by A. Ron [Constructive Approximation 4, No.4, 357-378 (1988; Zbl 0674.41005)] and encompasses a more general algebraic study of cardinal E-splines. The authors’ approach is based on some new bounds and formulas for the dimension of certain intersections of null spaces of commuting linear operators. In particular, this achieves a characterization of the local linear independence of translates of exponential cube spline as also enables them to study local algebraic properties of functions spanned by them. The paper includes analysis of some algorithms based on the concept of discrete exponential splines. The combinatorial interpretation of the discrete splines and relationship to their continuous counterparts leads to interesting combinatorial applications for enumerating the number of solutions to linear diophantine systems.
