Ebook: Recent Advances in Operator Theory and Related Topics: The Béla Szökefalvi-Nagy Memorial Volume

((keine ö-Punkte, sondern 2 accents aigus auf dem o in Szökefalvi, s. auch Titel!))

In August 1999, an international conference was held in Szeged, Hungary, in honor of Béla Szökefalvi-Nagy, one of the founders and main contributors of modern operator theory. This volume contains some of the papers presented at the meeting, complemented by several papers of experts who were unable to attend. These 35 refereed articles report on recent and original results in various areas of operator theory and connected fields, many of them strongly related to contributions of Sz.-Nagy. The scientific part of the book is preceeded by fifty pages of biographical material, including several photos.
