Approximation properties for Baskakov-Kantorovich-Stancu type operators   based on q- integers
  In this paper, we give an interesting generalization of the Stancu type Baskakov-Kantorovich operators based on the q-integers and investigate their approximation properties. Also, we obtain the estimates for the rate of convergence for a sequence of them by the weighted modulus of smoothness.
