Nonsmooth Analysis is a relatively recent area of mathematical analysis. The literature about this subject consists mainly in research papers and books. The purpose of this book is to provide a handbook for undergraduate and graduate students of mathematics that introduce this interesting area in detail.

Includes different kinds of sub and super differentials as well as generalized gradients
Includes also the main tools of the theory, as Sum and Chain Rules or Mean Value theorems
Content is introduced in an elementary way, developing many examples, allowing the reader to understand a theory which is scattered in many papers and research books

"...starting from the very beginning, adopting a slow, easy to follow linear development and reaching to a self-contained theory...oriented towards undergraduate students, as a first quick introduction to the topic." --MathSciNet"...devoted to presenting the theory of the subdifferential of lower semicontinuous functions which is a generalization of the subdifferential of convex functions...a good reference for researchers in optimization and applied mathematics." --Zentralblatt MATH, Sep-14
