From the reviews: "The account is quite detailed and is written in a
manner that will appeal to analysts and numerical practitioners
alike...they contain everything from rigorous proofs to tables of
numerical calculations.... one of the strong features of these
books...that they are designed not for the expert, but for those who
whish to learn the subject matter starting from little or no
background...there are numerous examples, and counter-examples, to back
up the theory...To my knowledge, no other authors have given such a
clear geometric account of convex analysis." "This innovative text is
well written, copiously illustrated, and accessible to a wide audience"
