The Best Uniform Rational Approximation: Applications to Solving Equations Involving Fractional powers of Elliptic Operators
Stanislav Harizanov, Raytcho Lazarov, Svetozar Margenov +1
In this paper we consider one particular mathematical problem of this large area of fractional powers of self-adjoined elliptic operators, defined either by Dunford-Taylor-like int…

Analysis of numerical methods for spectral fractional elliptic equations based on the best uniform rational approximation
Stanislav Harizanov, Raytcho Lazarov, Pencho Marinov +2
Here we study theoretically and compare experimentally an efficient method for solving systems of algebraic equations, where the matrix comes from the discretization of a fractiona…
