The historico-scientific context is outlined, including the links with other contemporary seminars, such as the S.Yu. Maslov’s seminar and the seminar on mathematical logic at the Leningrad Branch of the Steklov Mathematical Institute (LOMI); the ideas developed at the seminar and main results represented by scientific publications are considered. The pedagogical role of the seminar (its formative influence on young researchers), the organizational talent of R.I.
