UNN professor presents keynote lecture at mathematics conference in India
Renowned Russian scientist, Professor Yaroslav Sergeyev from the UNN Institute of Information Technology, Mathematics and Mechanics, was the keynote lecturer at the International Conference on Modern Mathematical Methods and High-Performance Computing in Science & Technology (M3HPCST 2026) in Mathura, India. His report was focused on calculations with infinitely large and infinitely small numbers.
Professor Yaroslav Sergeyev is widely known in Russia and internationally for his breakthrough results in two research fields. The first of them concerns methods for solving global optimization problems, and the second field, numerical calculations on a supercomputer with infinitely large and infinitely small quantities, was created by Yaroslav Sergeyev in the early 2000s.
Global optimization problems are exceptionally complex and are frequently encountered in computational practice (optimal design, machine learning and artificial intelligence, control of complex nonlinear systems, optimal control, etc.). Professor Yaroslav Sergeyev has been working on this topic for over 40 years. From 2017 to 2021, he served as the President of the International Society for Global Optimization. The numerical methods developed by Yaroslav Sergeyev and his team hold a leading position in the world and have set records in several classes of problems. In July 2023, Professor Yaroslav Sergeyev received the prestigious Constantin Carathéodory Prize of the International Society of Global Optimization, which is awarded bi-annually for fundamental contributions to the theory, algorithms, and applications of global optimization.
The computational methodology with infinitely large and infinitely small numbers proposed by Yaroslav Sergeyev has also gained significant recognition. Over twenty years of research, his Infinity Arithmetic has proven to be fruitful in various fields, including numerical analysis, operations research, computation theory, optimization, cellular automata theory, infinite game theory, probability theory, and even category theory. In all these areas, Infinity Arithmetic provides effective research tools that allow for a new perspective on known problems, the discovery of new or more efficient solutions compared to traditional ones, and the derivation of new generalizations for such problems.
Professor Sergeyev's scientific achievements have received considerable international acclaim.He has been honoured with the Pythagoras Prize (Italy, 2010), the Khwarizmi International Award from the Iranian government (2017), the MAIK "Nauka" Prize for the monograph "Diagonal Methods of Global Optimization" by Ya.D. Sergeyev and D.E. Kvasov, published in 2008, and other awards. He serves as the editor-in-chief of the international journal "Operations Research Forum" published by Springer and is a member of the editorial boards of three Russian and eleven international scientific journals in the field of applied mathematics and computer science.
