Approximation of functions of $n$ variables by quasipolynomials
Yu. A. Brudnyi
Abstract:
Approximation of functions of $n$ variables is studied by means of infinite-dimensional subspaces of singular functions of a special form (quasipolynomials). In particular, best approximation is examined by means of these subspaces, and both direct and converse theorems are proved.
