    • High-order two and three level schemes for solving fractional powers of elliptic operators 

      Čiegis, Raimondas; Vabishchevich, Piotr (Numerical mathematics and advanced applications ENUMATH 2019: European conference, Delft University of Technology, Egmond aan Zee, The Netherlands, September 30 - October 4, 2019, 2021)
      In this paper we develop and investigate numerical algorithms for solving the fractional powers of discrete elliptic operators with Vh a finite element or finite difference approximation space. Our goal is to construct ...
