James C. Robinson is a professor in the Mathematics Institute at the University of Warwick. He has been the recipient of a Royal Society University Research Fellowship and an Engineering and Physical Sciences Research Council (EPSRC) Leadership Fellowship. He has written six books in addition to his many publications in infinite-dimensional dynamical systems, dimension theory, and partial differential equations.
'This excellent introduction to functional analysis brings the
reader at a gentle pace from a rudimentary acquaintance with
analysis to a command of the subject sufficient, for example, to
start a rigorous study of partial differential equations. The
choice and order of topics are very well thought-out, and there is
a fine balance between general results and concrete examples and
applications.' Charles Fefferman, Princeton University, New
Jersey
'An Introduction to Functional Analysis covers everything that one
would expect to meet in an undergraduate course on this elegant
area and more, including spectral theory, the category-based
theorems and unbounded operators. With a well-written narrative and
clear detailed proofs, together with plentiful examples and
exercises, this is both an excellent course book and a valuable
reference for those encountering functional analysis from across
mathematics and science.' Kenneth Falconer, University of St
Andrews, Scotland
'This is a beautifully written book, containing a wealth of worked
examples and exercises, covering the core of the theory of Banach
and Hilbert spaces. The book will be of particular interest to
those wishing to learn the basic functional analytic tools for the
mathematical analysis of partial differential equations and the
calculus of variations.' Endre Suli, University of Oxford
'… this is a valuable book. It is an accessible yet serious look at
the subject, and anybody who has worked through it will be rewarded
with a good understanding of functional analysis, and should be in
a position to read more advanced books with profit.' Mark Hunacek,
The Mathematical Gazette
