On optimal quadrature formulae
TL;DR: In this article, a procedure to construct quadrature formulae which are exact for solutions of linear differential equations and are optimal in the sense of Sard is discussed, and necessary and sufficient conditions under which such formularae do exist.

On an optimal quadrature formula in the sense of Sard
TL;DR: The obtained optimal quadrature formula is exact for the trigonometric functions sinx and cosx and is investigated order of the convergence of the optimal formula and proves an asymptotic optimality of such a formula in the Sobolev space.

Error bounds for Gauss-Turán quadrature formulae of analytic functions
TL;DR: The location on the contour where the modulus of the kernel attains its maximum value is investigated, and the kernel of Gauss-Thran quadrature formulas is studied.

Construction of optimal quadrature formulas for Fourier coefficients in Sobolev space L2(m)(0,1)$L_{2}^{(m)}(0,1)$
TL;DR: Using the S.L.Sobolev’s method, new optimal quadrature formulas of such type for N+1≥m are obtained in the L2(m)(0,1)$L_{2}^{(m)}(0, 1)$ space for numerical calculation of Fourier coefficients.

An Error Expansion for some Gauss–Turán Quadratures and L1-Estimates of the Remainder Term
TL;DR: In this paper, the error expansions in the Gauss-Turan quadrature formula were obtained in the case when f is an analytic function in some region of the complex plane containing the interval [−1,1] in its interior.
