Short biography of
G. Voronoї
Georgiy Voronoї
was born in the village Zhuravka (now Varva District, Chernihiv
Region of Ukraine) on April 16(28), 1868. He was graduated from the
Pryluky Gimnasia (High School) in 1885, and from the St.Petersburg
University in 1889. He was left at the university to prepare his Master
thesis. After defending the thesis in 1894 he became a Professor of
the Warsaw University. From autumn of 1898, G.Voronoї also became
Professor of the Warsaw Polytechnical Institute where he was a Dean
of Mechanics Faculty. Voronoї defended his doctorate thesis in 1897,
and in 1907 he was elected a Correspondence Member of the Petersburg
Academy of Sciences. In 1905-1907, both Warsaw University and
Warsaw Polytechnical Institute were closed because of revolutionary
events. At that time Donskoi Polytechnical Institute was founded in Novocherkassk
and Voronoї worked there as a Dean of the Mechanics Faculty.
Georgiy Voronoї kept ties with Zhuravka along all his life.
He came there every year during summer vacations, there he thought
about his research papers. Voronoї suffered from a disease of the
gallbladder, in autumn of 1908 his disease passed on to the acute form,
and Georgiy Voronoї died on November 7(20), 1908. He was buried
in Zhuravka according to his last will.
Scientific heritadge
G. Voronoї
worked mainly in the field of the Number Theory. His scientific
publications started several new directions of research in
analytic number theory, algebraic number theory, theory of functions,
he essentially contributed to geometry of numbers, a field introduced
by H.Minkowski. His thorough investigation of the Dirichlet-Voronoi
domain opened a broad range of
applications in science
and technology. Likewise, his investigations of perfect forms
were a significant contribution to the theory of quadratic
forms and greatly stimulated the research in this field of pure mathematics.
But only in our time the real significance of his works became fully
elucidated. His works gained considerable importance in the
last thirty years due to development of many modern fields of science
and the usage of "Voronoi diagrams" in many domains. The Complete
Voronoї Works (in three volumes) were published by the Institute
of Mathematics of Ukraine in 1952-53.
Voronoi diagrams were introduced to theoretical
computer science in the middle of the 1970s. Meanwhile, the Voronoi
diagram has become so ubiquitous in geometric algorithms design that
some people date the birth of computational geometry to this event.
A good percentage of papers in the computational geometry literature
is directly or indirectly concerned with Voronoi diagrams and their related
structures. They used now in different scientific investigations from
microbiology to cosmos, this mathematical object is used in hundreds
of articles and a number of comprehensive monographs, just to mention
the book by A.Okabe, B. Boots, K. Sugihara and Sung
Nok Chiu “Spatial Tessellations: Concepts and Applications
of Voronoi Diagrams” (Wiley, 2000, second ed.,672 pp.).
Extraordinary
popularity of Voronoi diagrams does not diminish the significance
of his other ideas and results. Almost each of his works has
now its continuation.
VD-conferences, devoted to Voronoi diagrams:
a)
1st International Symposium on Voronoi Diagrams in Science
and Engineering,
September, 2004 University of Tokyo, Tokyo, Japan
http://www.simplex.t.u-tokyo.ac.jp/~vd2004/index.html
b) 2nd International Symposium on Voronoi Diagrams
in Science and Engineering, October 2005, Hanyang University,
Seoul, Korea

http://www.comp.glam.ac.uk/GIS/ISVD07/
The Voronoї conferences, devoted
to the Number Theory and Spatial Tessellations held
in Kyiv, Ukraine.
The
Institute of Mathematics of the National Academy of Sciences of Ukraine together
with some others scientific and educational institutions of Ukraine
organized three International Voronoї conferences
(1993, 1998, 2003) . Web pages of the last two of them are:

http://www.imath.kiev.ua/~vo/voronoi/first-en.html
A special volume (in two books)
Voronoї’s Impact on Modern Science was
issued by the Institute of Mathematics in 1998.
