Complexity of approximation of Lipschitz functions
Sergey Borisovich Gashkov, J. V. Wegner · Moscow University Mathematics Bulletin · 2008
The attainability of the lower bound by order is proved for the complexity of a problem of approximation of Lipschitz functions by diagrams of functional elements in bases consisting of a finite number of Lipschitz functions and a continuum of constants from a bounded set.
