%X Since the assumption of strang's uniformity on the basis functions is replaced by the uniformity assumption on interpolated nodes, the opthnal approximablity error estimates are derived. Considering an extreme value of certain set function, the "inverse relations" of pieeewise polynomials also are achieved generally.
