nLab Israel Gelfand

Selected writings

Israel Moiseevich Gel’fand (Израиль Гельфанд, 1913–2009) played a preeminent role in Russian mathematics for many years. His legendary seminar in Moscow ran for 50 years, and set the pattern for many others, including Sullivan’s seminar at CUNY and Drinfeld’s at Chicago. His name is attached to many mathematical achievements, including

He is the author of a 6-volume treatise on distribution theory (various volumes in collaboration with Shilov, Vilenkin, Graev).
