From history of one unpublished paper of M. I. Kadets

Authors of paper put before themselves a problem: to acquaint the mathematical public with unpublished paper of the outstanding Soviet mathematician M.I.Kadets heading the Kharkov school, known for the works in the field of the theory of Banach spaces, to tell story of this paper. The given work continues paper of the author about part cooperation and interaction of teachers and scientists of the Tula state pedagogical university of L.N.Tolstoy and Michael Iosifovich Kadetsa's Kharkov school.
Under its management the Tula student which afterwards after training at Michael Iosifovich Kadetsa's Kharkov school became the candidate of physical and mathematical sciences conducted scientific work. Michael Iosifovich by right is considered one of founders of the theory of equivalent renormings of the Banach spaces, turned now in independent area. The Kharkov school Kadetsa has at that time become world-famous. M.I.Kadets generously shared the mathematical ideas with the pupils. In paper some joint outcomes received by M.I.Kadetsem and its pupil in 1988-1990 which prepared for the publication in the form of joint paper but then have not been published because of high insistence which was shown to itself by outstanding Soviet mathematician M. I. Kadets, to insistence which can be an example for modern youth, especially for scientific youth are reduced. The study was carried out at the expense of budgetary funds according to the state assignment of the Financial University No. 15841p-P8.
