Abstract: | Summary In the present work we extent the results in [RS] on CHIP, i.e. Cardinal Hermite Interpolation by the span of translates of directional derivatives of a box spline. These directional derivatives are that ones which define the type of the Hermite Interpolation. We admit here several (linearly independent) directions with multiplicities instead of one direction as in [RS]. Under the same assumptions on the smoothness of the box spline and its defining matrixT we can prove as in [RS]: CHIP has a system of fundamental solutions which are inLL2 together with its directional derivatives mentioned above. Moreover, for data sequences inlp(d), 1p2, there is a spline function inLp, 1/p+1/p=1, which solves CHIP.Research supported in part by NSERC Canada under Grant # A7687.
