On exponential convergence of Gegenbauer interpolation and spectral differentiation
نویسندگان
چکیده
This paper is devoted to a rigorous analysis of exponential convergence of polynomial interpolation and spectral differentiation based on the Gegenbauer-Gauss and Gegenbauer-Gauss-Lobatto points, when the underlying function is analytic on and within an ellipse. Sharp error estimates in the maximum norm are derived.

A Hybrid Approach to Spectral Reconstruction of Piecewise Smooth Functions
Consider a piecewise smooth function for which the (pseudo-)spectral coefficients are given. It is well known that while spectral partial sums yield exponentially convergent approximations for smooth functions, the results for piecewise smooth functions are poor, with spurious oscillations developing near the discontinuities and a much reduced overall convergence rate. This behavior, known as t...
متن کاملTrouble with Gegenbauer reconstruction for defeating Gibbs phenomenon: Runge phenomenon in the diagonal limit of Gegenbauer polynomial approximations
To defeat Gibbs phenomenon in Fourier and Chebyshev series, Gottlieb et al. [D. Gottlieb, C.-W. Shu, A. Solomonoff, H. Vandeven, On the Gibbs phenomenon I: recovering exponential accuracy from the Fourier partial sum of a nonperiodic analytic function, J. Comput. Appl. Math. 43 (1992) 81–98] developed a ‘‘Gegenbauer reconstruction’’. The partial sums of the Fourier or other spectral series are ...
متن کاملPadé-Gegenbauer suppression of Runge phenomenon in the diagonal limit of Gegenbauer approximations
Boyd shows in [3] that for a function with singularities in the imaginary plane, the Gegenbauer expansion of the function may have Runge-type oscillations so large that all hope of convergence for the method is lost. We consider the use of Padé-Gegenbauer interpolants to resolve these oscillations. We describe a fast interpolation-based reconstruction for computing the Padé-Gegenbauer approxima...
متن کاملRecovering exponential accuracy from collocation point values of smooth functions with end-point singularities
Gibbs phenomenon is the particular manner how a global spectral approximation of a piecewise analytic function behaves at the jump discontinuity. The truncated spectral series has large oscillations near the jump, and the overshoot does not decay as the number of terms in the truncated series increases. There is therefore no convergence in the maximum norm, and convergence in smooth regions awa...
متن کاملConvergence of Integro Quartic and Sextic B-Spline interpolation
In this paper, quadratic and sextic B-splines are used to construct an approximating function based on the integral values instead of the function values at the knots. This process due to the type of used B-splines (fourth order or sixth order), called integro quadratic or sextic spline interpolation. After introducing the integro quartic and sextic B-spline interpolation, their convergence is ...
