Rates of convergence of Chlodovsky-Kantorovich polynomials in classes of locally integrable functions
In this paper we establish an estimation for the rate of pointwise convergence of the Chlodovsky-Kantorovich polynomials for functions f locally integrable on the interval [0,∞). In particular, corresponding estimation for functions f measurable and locally bounded on [0,∞) is presented, too.
Approximation properties of the partial sums of Fourier series of some almost periodic functions

Properties of some bivariate approximants.
The smoothness and approximation properties of certain discrete operators for bivariate functions are examined.
On the rates of convergence of Chlodovsky-Kantorovich operators and their Bézier variant
In the present paper we consider the Bézier variant of Chlodovsky-Kantorovich operators for functions measurable and locally bounded on the interval . By using the Chanturiya modulus of variation we estimate the rate of pointwise convergence of at those at which the one-sided limits , exist.
