Approximating B-continuous functions using GBS operators of Bernstein–Schurer–Stancu type based on q-integers

A GBS (Generalized Boolean Sum) operator of Bernstein–Schurer–Stancu type based on q-integers is constructed and the approximation of B-continuous functions using the above operator is studied. A uniform convergence theorem is established and the rate of convergence in terms of mixed modulus of continuity is determined.
