This book examines some recent developments in the theory of
$C^*$-algebras, which are algebras of operators on Hilbert spaces.
An elementary introduction to the technical part of the theory is
given via a basic homotopy lemma concerning a pair of almost
commuting unitaries. The book presents an outline of the background
as well as some recent results of the classification of simple
amenable $C^*$-algebra, otherwise known as the Elliott program.
This includes some stable uniqueness theorems and a revisiting of
Bott maps via stable homotopy. Furthermore, $KK$-theory related
rotation maps are introduced. The book is based on lecture notes
from the CBMS lecture sequence at the University of Wyoming in the
summer of 2015.
