## On discrete $$q$$-beta operators.(English)Zbl 1252.41014

The authors propose and study a $$q$$-analogue of the discrete beta operators. They establish some global direct error estimates for such operators in terms of the second order Ditzian-Totik modulus of smoothness. At the end, they study the limiting case of these $$q$$-beta operators.
