This monograph presents the state of the art of convexity, with an emphasis to integral representation. The exposition is focused on Choquet's theory of function spaces with a link to compact convex sets. An important feature of the book is an interplay between various mathematical subjects, such as functional analysis, measure theory, descriptive set theory, Banach spaces theory and potential theory. A substantial part of the material is of fairly recent origin and many results appear in the book form for the first time. The text is self-contained and covers a wide range of applications.

Commentaire
"Incorporating many original results of the authors, the book is addressed both to students who can find a clear and thorough presentation of the basics of the integral theory, as well as for the advanced readers who find a substantial amount of recent results, appearing for the first time in book form."
