Welcome to Real Analysis: Continuity and Calculus, Distance and Dynamics

MAA Press: An Imprint of the American Mathematical Society
Welcome to Real Analysis is designed for use in an
introductory undergraduate course in real analysis. Much of the
development is in the setting of the general metric space. The book
makes substantial use not only of the real line and
\(n\)-dimensional Euclidean space, but also sequence and
function spaces. Proving and extending results from single-variable
calculus provides motivation throughout. The more abstract ideas come
to life in meaningful and accessible applications. For example, the
contraction mapping principle is used to prove an existence and
uniqueness theorem for solutions of ordinary differential equations
and the existence of certain fractals; the continuity of the
integration operator on the space of continuous functions on a compact
interval paves the way for some results about power series.
The exposition is exceedingly clear and well-motivated. There are
a wide variety of exercises and many pedagogical innovations. For
example, each chapter includes Reading Questions so that students can
check their understanding. In addition to the standard material in a
first real analysis course, the book contains two concluding chapters
on dynamical systems and fractals as an illustration of the power of
the theory developed.
