Program
Monday, April 23, 14:00–16:00
Mykhailo Drahomanov National Pedagogical University
Kyiv, 9 Pyrohova St., room 448
Demonstration of the film “Georgy Voronoï, Ukrainian and Polish Mathematician” (produced by Chernihiv Television and Radio Company in 2013, 20 min). Short talks of scientists and open discussion are also planned.
Wednesday, April 25, 14:00–15:00
Institute of Mathematics of the National Academy of Sciences of Ukraine
Kyiv, 3 Tereschenkivska St., room 305 (conference hall)
Professor Mykola Pratsiovytyiʼs lecture “Geometrical Mosaics of the Great Ukrainian. Towards 150th Anniversary of Professor Georgy Voronoï” on the General Meeting of Department of Mathematics (National Academy of Sciences of Ukraine)
Friday, April 27
Zhuravka (Varva District, Chernihiv Region)
Trip from Kyiv to Zhuravka, where Georgy Voronoï was born and buried
During the events on April 23 and 25 a book exhibition will be open also. Academic publications related to Georgy Voronoïʼs research topics will be presented at the exhibition.
Admission to all events is free provided you register online [closed]. Number of seats is limited.
Recall that April 28, 2018 is 150th anniversary of Georgy Voronoï. He was a Doctor of Mathematics, Professor of Warsaw University, Corresponding Member of Saint Petersburg Academy of Sciences. Georgy was born in a small town Zhuravka, Poltava Province of that time, (1868) and graduated from Saint Petersburg University (1889). His papers are dedicated to number theory and calculus. Voronoï is a co-founder of a new field of mathematics, namely, geometry of numbers. Mathematical objects named after him, Voronoi diagrams, are extensively used in modern science and engineering for computer graphics, geometric modeling, design of robots, pattern recognition, research in artificial intelligence, design of geographic information systems, etc.
In 2018, Ukraine celebrates the 150th anniversary of Georgy Voronoï at the national level (in accordance to the Regulation of Verkhovna Rada of Ukraine “On Celebration of Memorable Dates and Anniversaries in 2018” of 08.02.2018 No. 2287-VIII).

In Kyiv, world famous scientist Georgy Voronoï is commemorated
Special meeting devoted to 150th anniversary of world famous mathematician of Ukrainian origin Georgy Voronoï was held on April 23 at the Department of Physics and Mathematics of the Mykhailo Drahomanov National Pedagogical University.
The film “Georgy Voronoï, Ukrainian and Polish Mathematician” (produced by Chernihiv Television and Radio Company in 2013, directed by Tetiana Myrhorodska) was demonstrated. Although screenplay contains some mistakes and inaccuracies, one can obtain information about life, research and teaching of the genius scientist.
Guests of the event spoke how they use Voronoïʼs results in their research work.
Academician Yaroslav Yatskiv, Director of the Main Astronomical Observatory of the NAS of Ukraine, and his co-workers Dr. Daria Dobrycheva and Dr. Iryna Vavilova spoke about mathematical methods to study large-scale structures and evolution of galaxies. Prof. Oleksandr Rud (Georgy Kurdyumov Institute for Metal Physics of the NAS of Ukraine) said how to use Voronoï polyhedral analysis for study of disordered systems.
Dr. Halyna Syta (Mykhailo Drahomanov National Pedagogical University) researched Georgy Voronoïʼs work and history of his family for many years. She recalled how a group of mathematicians from Kyiv visited Zhuravka in 1982 for the first time: they saw a grave of the scientist, and the house of Voronoï family existed at that time. She is also got acquainted with Georgyʼs daughter Maria Vorona‑Vasylenko, when Maria lived in Boryspil. Researcher cites Mariaʼs words, “In our family, we knew do not think about wealth (although we never were rich) and do not think about glory, but about glory of Ukraine”.
Halyna Syta also recalled a famous Lina Kostenkoʼs lecture “The humanitarian aura of the nation” and discussed scientific aura of the nation. This means that we should respect people that contributed to scientific and engineering progress of mankind. Dr. Olga Pshenychna (Ivan Frantsevych Institute for Problems in Materials Science of the NAS of Ukraine) supported this opinion. She believes that mind, intellectuals, and real elite of the nation are very undervalued in modern Ukraine. Zhuravka is well known for Olga because her parents were born in this beautiful village, and it is also undervalued by its residents.
Prof. Massimo Capaccioli (University of Naples Federico II) is very impressed by this event. His student showed Voronoï mosaics to him, when Capaccioli was already a university professor. “But I did not know anything about Voronoï. Now I know that he is Ukrainian. So, I am happy to visit Ukraine even more,” Capaccioli said.

Trip to Zhuravka
A group of scientists from Kyiv visited Zhuravka on April 27.
Researchers and post-graduates of the Mykhailo Drahomanov National Pedagogical University, of the Institute of Mathematics and of the Main Astronomical Observatory of the National Academy of Sciences of Ukraine participated at the special events organized at the local school, visited the school local lore museum and the grave of Georgy and Theodosiy Voronoïs, and a homestead where an oak-tree planted by Georgy Voronoï still grows.
