	3	ASYMPTOTIC BEHAVIOR OF THE ECKHOFF METHOD FOR CONVERGENCE ACCELERATION OF TRIGONOMETRIC INTERPOLATION显示文摘Convergence acceleration of the classical trigonometric interpolation by the Eckhoff method is considered, where the exact values of the 'jumps' are approximated by solution of a system of linear equations. The accuracy of the 'jump' approximation is explored and the corresponding asymptotic error of interpolation is derived. Numerical results validate theoretical estimates.

	4	ASYMPTOTIC BEHAVIOR OF THE ECKHOFF APPROXIMATION IN BIVARIATE CASE显示文摘The paper considers the Krylov-Lanczos and the Eckhoff approximations for recovering a bivariate function using limited number of its Fourier coefficients. These approximations are based on certain corrections associated with jumps in the partial derivatives of the approximated function. Approximation of the exact jumps is accomplished by solution of systems of linear equations along the idea of Eckhoff. Asymptotic behaviors of the approximate jumps and the Eckhoff approximation are studied. Exact constants of the asymptotic errors are computed. Numerical experiments validate theoretical investigations.	Arnak Poghosyan	2012	Analysis in Theory and Applications2012，28，4：	0
