Raports on Mathematical Physics publish papers in theoretical physics which present a rigorous mathematical approach to problems of quantum and classical mechanics and field theories, relativity and gravitation, statistic physics, thermodynamics, mathematical foundations of physical theories etc. Preferred are papers using modern methods of functiual analysis, probability theory, differential geometry, algebra and mathematical logic (approximately in this order of prefercence). Papers without direct connection with physics will not be accepted.Manuscripts should be concise ,but possiblu complete in presentation and discussion, to by comprehensible not only for mathematicans, but also for mathematically oriented theretical physicists. All papers should describe original work and be written in English.
