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. . . [is] that they are designed not for the expert, but for those who wish 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“
