We approximate the solution of initial boundary value problems for equations of the form Au'(t) =: B(t, u(t)), t E [0, t\*]. A is a linear, selfadjoint, positive definite operator on a Hilbert space (H, (-, .)) and B is a possibly nonlinear operator. We discretize in space by finite element methods

โฆ Synopsis
In this paper we present a family of explicit formulas for the numerical solution of differential equations of fractional order. The proposed methods are obtained by modifying, in a suitable way, Fractional-Adams-Moulton methods and they represent a way for extending classical Adams-Bashforth multistep methods to the fractional case. The attention is hence focused on the investigation of stability properties. Intervals of stability for k-step methods, k = 1, . . . , 5, are computed and plots of stability regions in the complex plane are presented.
