Gregory G. Menshikov has turned 70
Professor Dr. Gregory Menshikov was born in St.Petersburg (then Leningrad) in
1931. His childhood was greatly affected by the Second World War. Like many other
kids from Leningrad, Gregory was evacuated from the city to the Moscow region.
After the war, he returned back, ﬁnished high school, and entered the Department of
Mathematics and Mechanics of the Leningrad State University. In 1954, he received
a M.Sc. degree in Mathematics with honors.
In the beginning of his research career, Gregory Menshikov considered Com-
putational Mathematics and Radio Engineering as two main areas of interest. At
that time, such a combination was not unusual, because a lot of computations were
performed by analog computers and specialized digital electronic devices.
In 1962, Gregory Menshikov completed his postgraduate studies in Leningrad
Electrotechnical Institute of Communication and earned his Ph.D. degree from
Leningrad Institute of Precision Mechanics and Optics. In his dissertation, he devel-
oped a theoretical basis for digital devices for the numerical solution of ordinary
differential equations and for computation of functional polynomials.
After obtaining a Ph.D. degree, Gregory Menshikov continued his research in
the theory of binary approximation. In 1968 Gregory Menshikov ﬁnished his post-
doctoral studies at the Electrotechnical Institute of Communication and received a
D.Sc. (Habilitation) degree in Theoretical Radio Engineering.
After 1968, Gregory Menshikov continued his research in the areas of computa-
tional mathematics and radio engineering with emphasis on mathematics. In 1972,
he accepted an invitation to join the Department of Mathematics in Leningrad Elec-
trotechnical Institute where he worked until 1984. Shortly after his arrival, he was
promoted to the rank of a Full Professor. During these years, his main research areas
were theory of ordinary differential equations and theory of approximation.
In the mid-80’s, a lucky chance resulted in Gregory Menshikov’s acquaintance
with interval mathematics and, since that time, all his professional activity is insep-
arable from the interval analysis and its applications. Gregory Menshikov can, thus,
be called one of the ﬁrst “intervalists” in Russia. He applied interval approach to
the analysis of pulse radio engineering devices. In addition to his research, Profes-
sor Menshikov developed and taught numerous courses in Differential Equations,
Mathematical Analysis, Functional Analysis, Methods of Computations, Interval
Computations, Enclosure methods, and many other areas.
In 1984, Gregory Menshikov was invited to chair the Department of Mathe-
matical Theory of Microprocessor Control Systems, part of the Faculty of Applied
Mathematics and Control Processes at St.Petersburg State University. He has been
