An optimal class of eighth-order iterative methods based on Kung and Traub's method with its dynamics

Gunar Matthies, Mehdi Salimi, Somayeh Sharifi +1

In this paper, we present a three-point without memory iterative method based on Kung and Traub's method for solving non-linear equations in one variable. The proposed method has e…

Unconditional and quasi-greedy bases in $L_{p}$ with applications to Jacobi polynomials Fourier series

Fernando Albiac, José L. Ansorena, Óscar Ciaurri +1

We show that the decreasing rearrangement of the Fourier series with respect to the Jacobi polynomials for functions in $L_{p}$ does not converge unless $p = 2$ . As a by-product of our…

Fractional discrete Laplacian versus discretized fractional Laplacian

Ó. Ciaurri, L. Roncal, P. R. Stinga +2

We define and study some properties of the fractional powers of the discrete Laplacian $(- Δ_{h})^{s}, on Z_{h} = h Z,$ for $h > 0$ and $0 < s < 1$ . A comparison b…
