Groups,This chapter begins by reviewing some basic group theory—subgroups, quotients, homomorphisms, and isomorphisms—in order to have a basis for discussing Lie groups in general and simple Lie groups in particular.

The exponential map,This line is (in a sense we explain below) the . to the circle at its identity element 1. And, in fact, any Lie group has a linear space (of the same dimension as the group) as its tangent space at the identity.

Topology,One of the essential properties of a Lie group . is that the product and inverse operations on . are . functions. Consequently, there comes a point in Lie theory where it is necessary to study the theory of continuity, that is, .. Our journey has now reached that point.
