✦ Synopsis


For k=2 and 3, B. Shekhtman proved that n+k&1 is the smallest dimension of a subspace, F C(R n ) that can interpolate to k specified real values at k distinct points in R n . Here we characterize such spaces that interpolate at a few points. The characterization provides an economical proof of Shekhtman's theorems, as well as establishing new properties of these spaces.

The so-called "Padua points" give a simple, geometric and explicit construction of bivariate polynomial interpolation in the square. Moreover, the associated Lebesgue constant has minimal order of growth O(log 2 (n)). Here we show four families of Padua points for interpolation at any even or odd de
