Optimal Quadrature Formulae for Periodic Functions

1974
We consider \( {\tilde H_\beta }: = \left\{ {f\left| {2\pi - } \right.} \right. \) periodic, holomorphic in a strip of width 2β, real on ℝ with \( {\left| f \right|_\beta }: = \mathop {\sup }\limits_{\left| y \right| < \beta } \left| {\operatorname{Re} f\left( {x + iy} \right)} \right| < \infty \} \) and \( \tilde H_\beta ^1 = \left\{ {f \in {{\tilde H}

On the existence of optimal quadrature formulae for smooth functions

Calcolo, 1979
A general method showing the existence of optimal quadrature formulae with preassigned multiplicities of the nodes for classes of smooth functions is demonstrated. The main result is applied to the Hardy spaceH ∞ of analytic functions.

Widths and optimal quadrature formulas for convolution classes

Ukrainian Mathematical Journal, 1991
We compute Kolmogorov widths in the space L1 for classes of periodic functions representable in the form of a kernel convolution that does not increase the number of sign changes with values in a given transposition invariant set of functions, and solve the optimization problem for quadrature formulas in these classes.

An optimal quadrature formula of closed type

Yokohama mathematical journal, 2003
An optimal 3-point quadrature formula of closed type is derived. The optimality is considered with respect to a given way of estimation of its error.
