The Moment Problem

Konrad Schmüdgen is professor at the University of Leipzig, Germany. He discovered the strict Positivstellensatz and developed in this manner the interplay between real algebraic geometry and moment problems. He obtained a number of fundamental results on full and truncated multidimensional moment problems.

"The virtue of Schmüdgen's graduate textbook is that it lays solid foundations for any further explorations, theoretical or applied, in the complex and dynamical realm of moment problems. ... This volume will definitely be the reference to moment problems for several future generations." (Mihai Putinar,Mathematical Reviews, 2018)

"The bibliography includes many older and newer titles, the author being one of the main contributors in the last forty years. The book is well-written and it can be considered as an up-to day reference book for the use of both beginners and confirmed researchers, oriented not only to the domain of moment problems but also to other branches of analysis, or of mathematics, in general."
