C. Heil:
METRICS, NORMS, INNER PRODUCTS, AND OPERATOR THEORY,
Birkhäuser/Springer, Cham, 2018 (xxi + 359 pp.).
Mathematics deals with many types of objects---shapes, numbers, points
in Euclidean space, functions, linear transformations, graphs,
to name only a few.
However, these objects do not exist in isolation, and by looking at the
properties of a related family or space of objects we often
gain new understanding.
In analysis, which in many ways is the "science of functions",
the three main types of families that we encounter are metric spaces,
normed spaces, and inner product spaces.
This text is a self-contained introduction to these spaces, and to the
operators that transform objects in one space
(which are often themselves functions) into objects in another space.
The intended reader of this text is a motivated student who is ready
to take an upper-level, proof-based undergraduate mathematics course.
No knowledge of measure theory or advanced real analysis is required.

Quote: "The text is clearly and carefully written and is enhanced by an extensive list of problems, presented in increasing order of difficulty."

Quote: "Each subchapter is endowed with a number of exercises.
These vary in difficulty and type.
Very interesting, for the classroom as well as for independent study,
is the combination of more computational problems ...
proof-oriented problems ...
and problems that help students to think ..."

Chapter 8: Integral Operators.
While the main text does not require knowledge of Lebesgue measure
and the Lebesgue integral, this chapter includes results that
do depend on that material.
- A collection of
Extra Material and Problems is available.
This is a somewhat random assembly of results, problems,
extra sections, and other material that is related to the text
but did not make it into the text proper.
