ABSTRACT
In this chapter we discuss various aspects of non-chaotic systems, that will be helpful
in analysing other, more complex, systems. In section 7.1 we define conservative and
Hamiltonian systems, while in section 7.2 we give a brief account of linear systems
of differential equations, and the qualitative behaviour of their solutions near the
equilibrium point. These are models for the local behaviour of more complicated
systems near their equilibrium points.
