Письма соболезнования по уходу из жизни М.Г. Ревнивцева

— I am deeply regret to hear from Irek Khamitov that Dr. Mikail Revnivtsev has passed away. We lost a friend and a scientist. His works will be kept in the common memory of the civilisation, and his memories in his friends. 

Please accept my condolences.
