Brest State University has celebrated its 60th anniversary. The Muscovite Eugeny Grebennikov, Doctor of Physics and Mathematics, Professor, is one of those who were especially welcome at the anniversary celebration. The scientist is active in his cooperation with many Belarusian institutions of higher education, and his relationships with Brest State University are already 30 years old. As a true scientist, he made his present to the university in the form of lectures at the Faculty of Mathematics.
In his time Eugeny Grebennikov was awarded two National Prizes of the USSR. In 1971 he gained recognition for his space research — the scientist offered a method of trajectory calculation for space objects that proved to be several times more effective than the one used at that time in the West.
His second prize, in 1983, professor Grebennikov received for the development of a multi-user computer system for higher education institutions of the USSR. Today he works as a principal research fellow at a computation centre.
— Russian mathematicians have retained their traditional connections with Belarusian colleagues, — remarked the Moscow scientist speaking to the students of Brest State University at the international mathematics conference held there. — I mean not only development of scientific contacts, but also good friendly relations between the institutes and universities of our countries.
Starting in the 50s, Russian and Belarusian mathematicians have been working on joint projects. It is at that time that the best soviet mathematicians from Leningrad and Sverdlovsk — Vladimir Krylov, Nikolai Yerughin and Eugeny Barbashin — came to work at the Academy of Science of Belarus. They established the Institute of Mathematics at the Academy that solved many applied problems including the ones in the spheres that had to do with the development of national economy of the republic and the country in general. Since that time the mathematical school in Belarus has been very strong.
—The topic of your speech at the conference was the problem of “stability of a bounded problem of space dynamics for eight objects”. Could you explain to laymen what it is all about?
— The planets of Solar system draw each other from Newton’s law. In the stellar system six planets symmetrically revolve around the central object — primary star — along one circumference. It is important to know the coordinates at which the eighth object maintains stability in this planetary system within the required time. This is necessary to predict possible collision, because the eighth object is a satellite sent from the Earth.
— Does your research have to do with defence business?
— Contemporary mathematics creates universal schemes that can be used not only in military industrial complex. Nowadays, for instance, findings in the dynamics of climate change are very topical. And we have some.
— Do Belarusian scientists help you?
— Yes, we keep informing our Belarusian colleagues about the problems and tasks that Russian scientists are trying to solve. And we leave no avenue unexplored, be it an international conference, getting academic qualification of candidates and doctors of science with the assistance of Russian scientists or just Russian professors’ lecturing at Belarusian institutions of higher education. Such cooperation is a prerequisite of our common success. A lot of my students and associates are working in Belarus. Thinking of the future, I realize that one should plant love for mathematics — the mother of all sciences — at a very young age. That is why, for example, I willingly accepted the offer of Brest NGO “Humanitarian Bridge” to become a scientific consultant on mathematics in the “Test” project within which schoolchildren of Brest region get additional training for the centralized testing.
— Is it true that one of the stars bears your name?
— Yes, it is. I would be glad if it became a guide for young mathematicians in Russia and Belarus. Indeed, mathematicians are, like planets, prone to interaction attraction.
