10.3 STABILITY IN THE LARGE
Stability when perturbations lie within certain finite limits.
10.4 STABILITY IN THE SENSE OF LAGRANGE
Stability of a system when the difference between perturbed and unperturbed states remains limited at any time.
10.5 STABILITY IN THE SENSE OF LYAPUNOV
Stability under perturbations of initial conditions only of a system.
10.6 STABILITY OF A FORM
Asymptotic stability of an equilibrium form of an elastic system.

10.8 STABILITY OF MOTION
Stability under small perturbations of displacements and/or velocities only of a system.
10.9 STABILITY OF THE FIRST APPROXIMATION
