Logarithmic norms and regular perturbations of differential equations
Jacek Banasiak · Annales Universitatis Mariae Curie-Sklodowska sectio A – Mathematica · 2020
In this note we explore the concept of the logarithmic norm of a matrix and illustrate its applicability by using it to find conditions under which the convergence of solutions of regularly perturbed systems of ordinary differential equations is uniform globally in time.
