Quantitative estimates for some modified Bernstein-Stancu operatorsVoichita Adriana Radu;
In paper  starting with the Bernstein operators, some Stancu type operators are constructed, named Bernstein-Stancu operators Cnf. The aim of this paper is to give some estimates for this operators, using the second order modulus of smoothness.
