Yuri Daletskii and the Development of Infinite Dimensional Analysis (original) (raw)

ing the next year, Yuri passed all school exams and was subsequently allowed to complete his university programme. He graduated in 1951, having written several research papers by that time. These works became the foundation of his PhD thesis completed under the supervision of Selim Krein, who played an important role in the development of the functional analysis school in Kiev. Soon after, Selim moved to Voronezh University. Yuri was very close to his teacher, always acknowledged his influence and remained in contact with him for his whole life. In 1951, Yuri took up a position at the Kiev Polytechnic Institute (The National Technical University of Ukraine at present), where he would remain for the entirety of his career, first as an assistant and eventually as a full professor and member of the Ukrainian Academy of Sciences. Yuri played a major role in forming the mathematical curriculum of the Institute. In the 70s and 80s he developed the mathematical programmes of the departments of Applied Mathematics, Mathematical Methods of System Analysis and the (new at that time) Faculty of Physics and Technology. Additionally, Yuri was one of the leaders of the successful independent postgraduate programme "Mathematics for Engineers", which was taught in Kiev for nearly two decades. Later, in the 90s, he also led mathematical programmes at the newly-founded Soros University. Very soon Yuri became a significant figure on the Kiev mathematical scene. At that time, mathematical life in Soviet research centres was concentrated around big inter-institutional seminars, famous examples being Gelfand's and Dobrushin's seminars in Moscow. Yuri supervised major Kiev seminars "Random processes and distributions in functional spaces" (together with A. Skorokhod) and "Algebraic Structures in Mathematical Physics". He was also an important contributor to the seminar "Group methods in solid-state physics". Due to his friendly and energetic personality and vast knowledge of a variety of mathematical fields, Yuri played a
