On lower bounds for the approximation of functions by local splines with nonfixed nodes

  • A. A. Shumeiko

Abstract

For functions integrable to the power \(\beta = (r + 1 + 1/p)^{ - 1} \) , we obtain asymptotically exact lower bounds for the approximation by local splines of degree r and defect k< r/2 in the metric of L p
