# Definition of fragility

What does it mean for a solution to a system of differential equations to be fragile?

A context for the term can be found here:

This is taken from here in Mathematical Methods for Mechanics: A Handbook With MATLAB Experiments by Eckart Gekeler.

Does it mean it is small perturbations grow over time?
