Anatoly Samoilenko facts for kids

Anatoly Mykhailovych Samoilenko (born January 2, 1938 – died December 4, 2020) was a very important Ukrainian mathematician. He was a top member, called an Academician, of the National Academy of Sciences of Ukraine starting in 1995. He also led the Institute of Mathematics of the National Academy of Sciences of Ukraine as its Director from 1988.

About Anatoly Samoilenko

Anatoly Samoilenko was born in 1938 in a village called Potiivka in the Zhytomyr region of Ukraine. In 1955, he started studying geology at the Shevchenko Kyiv State University. He later switched to mathematics and graduated in 1960. Around this time, he also published his first scientific papers.

After finishing his advanced studies in 1963, Samoilenko earned his first higher degree (like a PhD). His research was about differential equations. He then started working at the Institute of Mathematics of the National Academy of Sciences of Ukraine. There, he worked with a famous scientist, Academician Yu. A. Mitropolskiy.

In just a few years, Samoilenko became a leading expert in the study of differential equations. In 1967, he earned his highest degree (like a second PhD) for his work on multifrequency oscillations. This work helped him become a well-known mathematician.

His Career and Teaching

From 1965 to 1974, Samoilenko was a senior researcher at the Institute of Mathematics. He also taught at the Shevchenko Kyiv State University. In 1974, he became a professor. In 1978, he was chosen as a Corresponding Member of the Academy of Sciences.

Samoilenko wrote an important book with his teachers, Academicians N. N. Bogolyubov and Mitropolskiy. This book made him famous around the world. He once said that being part of a strong scientific school helped him achieve world-class results. He believed it pushed young scientists to do their best work.

From 1974 to 1987, Samoilenko led the Department of Integral and Differential Equations at Kyiv State University. During this time, he and his students did a lot of important research. They published books on differential equations with delay and impulsive differential equations. These books are still widely used and cited by scientists today.

Leading the Institute

Since 1987, Samoilenko led the Department of Ordinary Differential Equations at the Institute of Mathematics. In 1988, he became the Director of the entire Institute of Mathematics of the National Academy of Sciences of Ukraine. This was a very productive time for him.

He wrote another key book about the theory of invariant tori in dynamical systems. This book helped create new ways to understand how these systems behave. He also worked with other scientists on topics like Lyapunov functions and boundary-valued problems. His work helped develop new ways to solve complex math problems.

Samoilenko wrote about 400 scientific papers. He also wrote 30 important books and 15 textbooks. Many of his works have been translated into other languages. His books have greatly helped both mathematical science and education.

His Impact on Mathematics

Samoilenko's research covered many important areas of mathematics. These included the study of qualitative theory of differential equations, nonlinear mechanics, and nonlinear oscillations. His work on multifrequency oscillations and impulsive systems was highly respected.

He founded a scientific school that is known worldwide. This school focuses on the theory of multifrequency oscillations and impulsive systems. As the Director of the Institute of Mathematics, he helped mathematics grow quickly in Ukraine. He also continued the great traditions of the famous Bogolyubov – Krylov – Mitropolskiy scientific school in Kyiv.

Samoilenko's contributions are so important that some mathematical ideas are named after him. These include the "Samoilenko numerical-analytic method" and the "Samoilenko – Green function."

Teaching and Mentoring

Anatoly Samoilenko cared a lot about training new scientists. For many years, he taught at Kyiv National University and the "Kyiv Polytechnic Institute" National Technical University. He guided many students working on their master's and doctoral degrees.

Even with his busy schedule as Director of the Institute, he found time for other activities. He was the President of a charity that supported mathematical sciences. He also helped create a charity to support talented children and young people from his home region.

Samoilenko found and taught many brilliant scientists. He created an international school for studying differential equations. Among his students, 33 became doctors (with highest degrees) and 82 became candidates (with advanced degrees) in math and physics. Many of them are now professors, deans, and university leaders. For example, his former students led the Department of Mechanics and Mathematics at Kyiv National University. Other students became rectors of major universities or presidents of academies of sciences in other countries.

Memberships and Awards

Samoilenko was a member of many important mathematical groups. These included the Ukrainian Mathematical Society and the American Mathematical Society. He also served on the editorial boards of many math journals in Ukraine and other countries. He was the editor-in-chief of the Ukrainian Mathematical Journal and the Nonlinear Oscillations journal.

He became a full member of the National Academy of Sciences of Ukraine in 1995. In 2002, he joined the European Academy of Sciences. He was also a Foreign Member of the Tajik Academy of Sciences starting in 2011.

Anatoly Samoilenko received many awards for his work. These included:

• Order of Friendship of Peoples (1984)
• Order of Merit of degree III (2003)
• Order of Prince Yaroslav the Wise of degree V (2008)
• A special Diploma from the Presidium of the Supreme Soviet of Ukraine (1987)
• Titles of an Honored Scientist of Ukraine (1998) and a Soros Professor (1998)

He also received several State Prizes:

• State Prize of Ukraine in the Field of Science and Engineering (1985 and 1996)
• State Prize of Ukraine in the field of education (2012)

Additionally, he was honored with several special prizes named after famous mathematicians:

• Ostrovsky Prize (1968)
• Krylov Prize (1981)
• Bogolyubov Prize (1998)
• Lavrentyev Prize (2000)
• Ostrogradsky Prize (2004)
• Mitropolskiy Prize (2010)
