Abstract:
Estimates of the remainders of certain quadrature formulas are obtained, in particular, of quadrature formulas with nodes that are the zeros of Chebyshev polynomials of the first kind in classes of differentiable functions characterized by a generalized modulus of continuity.
Key words:
weight function, shift operator, generalized modulus of continuity, $N$-width, Chebyshevtype quadrature formula.
