On some linear positive operators in polynomial weighted spaces. (English) Zbl 1064.41017
Summary: We consider certain linear positive operators $$A_n(f;q,r)$$ in polynomial weighted spaces of functions of one variable and we study approximation properties of these operators. We give theorems on the degree of approximation of functions from polynomial weighted spaces by the introduced operators, using norms of these spaces.
