Lyapunov Exponents of the Radii of Inscribed and Circumscribed Spheres of Solutions of Time-Invariant Linear Differential Equations with the Hukuhara Derivative.

We consider linear time-invariant differential equations with the Hukuhara derivative. We prove that if a solution of such an equation has a nonempty interior at the initial time, then the Lyapunov exponents of the radii of the inscribed and circumscribed spheres of this solution are strict and are equal to the minimum and maximum absolute values, respectively, of the eigenvalues of the coefficient matrix of the system.
