∗
(dedicated to 70th Birthday)
Vyacheslav Ivanovich Yanchevskii, a member of the National Academy
of Sciences of Belarus, was born in Minsk on July 9, 1948. In 1955 he
entered the secondary school no 27. Already in his school years he was
seriously interested in mathematics and in 1963 passed to a well-known
in Minsk school no 50. Then it was the only specialized secondary school
of physical and mathematical profile in Minsk. In 1964 V.I. Yanchevskii
entered the boarding school no 18 of physical and mathematical profile at
the Moscow State University (now it is the Kolmogorov school, a specialized
educational and scientific center of the MSU) and graduated from this
school in 1966. This school was created by the initiative of prominent
scientists A.N. Kolmogorov, I.K. Kikoin and I.G. Petrovskii in order to

prepare gifted schoolchildren for a future work as highly qualified scientists.
There the teachers taught to think and they took care on the personal
development of each pupil.
In 1966 V.I. Yanchevskii entered the mathematical faculty of the
Belarusian State University (BSU) and graduated with honours in 1971.
He started an active research still being a student. Having completed his
Ph.D. studies earlier than it was planned, since 1974 Vyacheslav Ivanovich
has been working at the Institute of Mathematics of the National Academy
of Sciences of Belarus (NAS of Belarus). Here he has passed a way from
a junior researcher to the head of the algebra department (since 1993).
In 1974 he has defended a candidate (Ph.D.) thesis with the theme
“The structure of the classical groups over finite dimensional skew fields”
(V.P. Platonov, a member of the Russian and Belarusian Academies of
Sciences, was his scientific advisor) and in 1980 he has defended a Doct. Sci.
thesis with the theme “Reduced unitary K-theory”. (Doctor of Sciences
is the highest scientific degree in the Soviet Union and some of new
independent states that were parts of the USSR.) In 1990 V.I. Yanchevskii
was assigned a professor title, in 2009 he was elected a corresponding
member and in 2014 a full member of the NAS of Belarus.
V.I. Yanchevskii is a scientist with a world name, a major expert in
algebraic geometry and algebra. The main fields of his research interests
are the theory of anisotropic algebraic groups, the algebraic geometry of
varieties of small dimension, the theory of Brauer groups of fields and
algebraic varieties, algebraic K-theory, and the theory of finite dimensional
algebras. Vyacheslav Ivanovich’s research yields a substantial contribution
to the progress of these fields: he has created reduced unitary and spinor
K-theories. Not long ago he has obtained a number of profound and in
many respects unexpected results that have led to a solution of two old and
well-known problems of algebraic geometry. Jointly with A. Wardsworth
(University of California-Berkeley, the USA) V.I. Yanchevskii has elab-
orated the reduced unitary K-theory of anisotropic Hermitian forms of
graduated division algebras which completed perennial research of a num-
ber of well-known experts from Germany, the USA, Great Britain, and
Russia. Using algebro-geometric methods, he together with U. Rehmann
(University of Bielefeld, Germany) and S.V. Tikhonov has solved the prob-
lem of the embeddability of arbitrary Adzumaya algebras into cyclic ones
with the same indices and exponents that has not been solved for 40 years.
Recently V.I. Yanchevskii has established the cyclicity of central simple
algebras over the function field of a projective plane with the ramification
in conics, cubics, and quadrics and has proved the existence of scalar

extensions that are the function fields of certain Severy-Brauer varieties
over which algebras have prescribed properties (are the twisted products
with fixed Galois groups, preserve the indices, have fixed exponents).
Vyacheslav Ivanovich is the author of more than 200 publications,
including articles in leading mathematical journals (“Doklady Akademii
nauk”, “Izvestiya Rossiiskoi akademii nauk. Seriya matematicheskaya”,
“Zapiski nauchnyh seminarov POMI”, “Proceedings of the Amer. Math.
Soc.”, “Transactions of the Amer. Math. Soc.”, “Journal of Algebra”, “Com-
munications in Algebra”, “Manuscripta Mathematica”, “Bulletin of the
Belgian Mathematical Society”, “Algebra and Discrete mathematics”, etc).
V.I. Yanchevskii is quite active in an international scientific collab-
oration. He was the belarusian coordinator or the head of a number of
international projects supported by the European Commission, INTAS,
and the Belarusian Republican Foundation for Fundamental Research,
many times he was invited for joint research to scientific centers of Ger-
many, Belgium, Switzerland, and Israel, gave talks on numerous important
international mathematical meetings including International congresses of
mathematicians (Madrid, 2006, Hyderabad, 2010, and Seoul, 2014) and
European mathematical congresses (Budapest, 1996 and Krakow, 2012).
Nowadays the importance of algebra (and especially, algebraic geom-
etry) for solving information defence problems grows quickly. This is
caused by using more and more complicated algebraic structures in mod-
ern and perspective cryptosystems. V.I. Yanchevskii was a supervisor of a
number of applied projects on information defense that were successfully
implemented in the framework of special state programs.
Vyacheslav Ivanovich spares much time and attention to teaching at
the BSU. He had been the head of the chair of geometry, topology and
the methodology of teaching mathematics at this university for more than
20 years, now he is the scientific supervisor of this chair and a member of
the Scientific Council of the Faculty of Mechanics and Mathematics of the
university. He has developed many original special courses on different
topics in algebra and algebraic geometry based on his own programs.
The level of the students’ mathematical culture, of their understanding of
fundamental notions is always very important for Vyacheslav Ivanovich.
That is why together with his colleagues he has written two seminal
textbooks: “Introduction into mathematics” (jointly with S.G. Kononov
and R.I. Tyshkevich) and “The basics of affine geometry” (jointly with
S.G. Kononov, A.V. Prokopchuk, and T.V. Tikhonova).
V.I. Yanchevskii has prepared 12 candidates of Sciences (Ph.D.). He
has many scientific-organizational activities, for many years he heads a

specialized council for thesis defense at the Institute of Mathematics of
the NAS of Belarus. He is a member of the Scientific council of the Be-
larusian Republican Foundation for Fundamental Research, of editorial
boards of the journals “Trudy Instituta matematiki” (“Proceedings of the
Institute of Mathematics”), “Vesti NAN Belarusi. Seryya fiz.-mat. navuk”
(“Proceedings of the NAS of Belarus. A series of physical and mathemat-
ical sciences”), and “Algebra and Discrete Mathematics”, a member of
the Editorial commission and of the section of technical, physical, and
mathematical sciences in the Premium commission of the NAS of Belarus.
Vyacheslav Ivanovich is a laureate of the NAS of Belarus prize (2008),
he was awarded the badge “For excellence in education in Belarus”, and
was assigned the title “A honored worker of the BSU”.
V.I. Yanchevskii is respected not only at the Institute of Mathematics,
but in many research centers in different countries as well where research
in algebra is conducted. This is a man of a broad erudition, he is fond
of history, literature, and music. Vyacheslav Ivanovich always takes care
on the growth of the professional qualifications and the cultural level of
young collaborators in the department of algebra.
In the jubilee day colleagues wish Vyacheslav Ivanovich to have good
health, new nice results and conjectures, talented and motivated pupils,
and good luck!
