Rezensionen

From the reviews of the first edition: "Distributions of certain point sets are in many respects important in approximation theory. ... Many classical theorems ... deal with such problems. This book collects a number of generalizations of these theorems. ... The book is written with great care. ... This monograph is a valuable addition to the library of any researcher in approximation theory. The topic is rather specialized, but the style and the importance of potential theory in the discipline, makes it also suited for an advanced course in approximation theory." (Simon Stevin Bulletin, Vol. 11 (1), 2004) "This book is devoted to discrepancy estimates for the zero of polynomials and for signed measures. ... A remarkable feature of the book is that most of the results in it are shown to be sharp. ... This work is a valuable monograph on a field that has attracted considerable interest in the recent past, and which has various applications in approximation theory and orthogonal polynomials." (Vilmos Totik, Bulletin of the London Mathematical Society, Vol. 35, 2003) "This book discusses in detail the discrepancy of signed measures ... . The detailed proofs and the rich reference make this book eligible for a self-study textbook and a reference book, too." (Béla Nagy, Acta Scientiarum Mathematicarum, Vol. 68, 2002)
