Abstract

The examples from Chapter  17 show that many geometrically defined Lie groups have several connected components. While only the connected component of the identity is accessible to the methods built on the exponential function, there are still tools to analyze nonconnected Lie groups. In the present chapter, we present some of these tools. The key notion is that of an extension of a discrete group by a (connected) Lie group.
