This title contains three volumes in one. Of the many well-known monographs in the series published by the Steklov Institute of the Academy of Sciences of the former U.S.S.R., only a few were originally published in a language other than Russian. Three of these works are reprinted in this volume: two major monographs in German - Untersuchungen einiger Integrale...unde ihre Anwendung auf Beugungserscheinungen, by Ignatowsky, Kreisscheibenkondensator, by Ignatowsky - and a very brief table (with an English introduction) - Table of a Special Function by Bursian and Fock.
