Computing the action of a matrix exponential on an interval via the -product approach
Stefano Pozza, Shazma Zahid
We present a new method for computing the action of the matrix exponential on a vector, \( e^{At}v \). The proposed approach efficiently evaluates the solution for all \( t \) with…
A -Product Approach for Analytical and Numerical Solutions of Nonautonomous Linear Fractional Differential Equations
Fabio Durastante, Pierre-Louis Giscard, Stefano Pozza
This article presents a novel solution method for nonautonomous linear ordinary fractional differential equations. The approach is based on reformulating the analytical solution us…
Best polynomial approximation for non-autonomous linear ODEs in the -product framework
Stefano Pozza
We present the first formulation of the optimal polynomial approximation of the solution of linear non-autonomous systems of ODEs in the framework of the so-called -product.…
Tridiagonalization of systems of coupled linear differential equations with variable coefficients by a Lanczos-like method
P. -L. Giscard, S. Pozza
We show constructively that, under certain regularity assumptions, any system of coupled linear differential equations with variable coefficients can be tridiagonalized by a time-d…
