On approximation of functions by product operators
In the present paper, two quite new reults on the degree of approximation of a function f belonging to the class Lip(α,r), 1≤ r <∞ and the weighted class W(Lr,ξ(t)), 1≤ r <∞ by (C,2)(E,1) product operators have been obtained. The results obtained in the present paper generalize various known...

| Summary: | In the present paper, two quite new reults on the degree of approximation of a function f belonging to the class Lip(α,r), 1≤ r <∞ and the weighted class W(Lr,ξ(t)), 1≤ r <∞ by (C,2)(E,1) product operators have been obtained. The results obtained in the present paper generalize various known results on single operators. |
