摘要

We introduce multivariate F-splines, including multivariate F-truncated powers T f (?|M) and F-box splines B f (?|M). The classical multivariate polynomial splines and multivariate E-splines can be considered as a special case of multivariate F-splines. We document the main properties of T f (?|M) and B f (?|M). Using T f (?|M), we extend fractional B-splines to fractional box splines and show that these functions satisfy most of the properties of the traditional box splines. Our work unifies and generalizes results due to Dahmen-Micchelli, de Boor-H?llig, Ron and Unser-Blu, and also presents a new tool for computing the integration over polytopes.
