Non-Isotropic Jacobi Spectral and Pseudospectral Methods in Three Dimensions

, 2015
Non-isotropic Jacobi orthogonal approximation and Jacobi-Gauss type interpolation in three dimensions are investigated. The basic approximation results are established, which serve as the mathematical foundation of spectral and pseudospectral methods for

Interpolating Refinable Functions And Wavelets For General Scaling Matrices

, 1997
This paper introduces a general procedure for constructing interpolating refinable functions for arbitrary dilation matrices. The key ideas are based on the construction presented in [24].

On the Proximinality of Ridge Functions

Sarajevo Journal of Mathematics, 2007
Using two results of Garkavi, Medvedev and Khavinson [7], we give sufficient conditions for proximinality of sums of two ridge functions with bounded and continuous summands in the spaces of bounded and continuous multivariate functions respectively.
