Abstract In the present paper, we study a new kind of Bernstein-Kantorovich-
type operators. Here, we discuss a uniform convergence estimate for this modified
form. Also, some direct estimates, which involve the asymptotic-type results, are
established. Some numerical examples which show the relevance of the results are
considered.
