A note on the convergence of multigrid methods for the Riesz-space equation and an application to image deblurring

Danyal Ahmad, Marco Donatelli, Mariarosa Mazza +2

In the past decades, a remarkable amount of research has been carried out regarding fast solvers for large linear systems resulting from various discretizations of fractional diffe…
