In fact, the integral representation theorems of Choquet and Bishop -de Leeuw together with the uniqueness theorem of Choquet inaugurated a new epoch in infinite-dimensional convexity. Initially considered curious and tech nically difficult, these theorems attracted many mathematicians, and the proofs were gradually simplified and fitted into a general theory. The results can no longer be considered very "deep" or difficult, but they certainly remain all the more important. Today Choquet Theory provides a unified approach to integral representations in fields as diverse as potential theory, probability, function algebras, operator theory, group representations and ergodic theory. At the same time the new concepts and results have made it possible, and relevant, to ask new questions within the abstract theory itself. Such questions pertain to the interplay between compact convex sets K and their associated spaces A(K) of continuous affine functions; to the duality between faces of K and appropr | | 出版日期 | Book 1971 | | 关键词 | Boundary; Convexity; Finite; Integral; Integrals; Konvexe Menge; algebra; function; functional analysis; oper | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-642-65009-3 | | isbn_softcover | 978-3-642-65011-6 | | isbn_ebook | 978-3-642-65009-3 | | copyright | Springer-Verlag Berlin Heidelberg 1971 |
