Numerical Approximation of Riesz-Feller Operators on
Carlota M. Cuesta, Francisco de la Hoz, Ivan Girona
In this paper, we develop an accurate pseudospectral method to approximate numerically the Riesz-Feller operator on , where , and $|γ|\le\min\{α, 2 -…

Numerical computation of the half Laplacian by means of a fast convolution algorithm
Carlota M. Cuesta, Francisco de la Hoz, Ivan Girona
In this paper, we develop a fast and accurate pseudospectral method to approximate numerically the half Laplacian of a function on , which is equivalent to…
