On March 27, students from Lyceums No. 1 and No. 3 of Kupiansk visited Kharkiv National University of Radio Electronics. The Department of Applied Mathematics participated in the event, during which Senior Lecturer Mykyta Hvozdiev conducted a business team game called “Fun Fishing”. During the event, the students learned about game theory, practiced making decisions under resource constraints, and mastered the selection of an appropriate strategy.

By implementing the principles of Sustainable Development Goal 4 – Quality Education, the university is forming an open and barrier-free educational space. This practical event served as a wonderful opportunity to support the students, help them adapt to difficult learning conditions, and demonstrate that applied science can be fascinating. This is an important step in overcoming learning losses and motivating future applicants to pursue higher education.

On March 26, students of the “Obdarovanist” Lyceum visited the Kharkiv National University of Radio Electronics. The Department of Applied Mathematics took part in the event, during which Senior Lecturer Mykyta Hvozdiev conducted a business team game called “Fun Fishing”. During the event, students of grades 8–11 learned about game theory, practiced making decisions under resource constraints, and mastered the selection of an appropriate strategy.

On the same day, Senior Lecturer Ravil Yanbekov and Assistant Andrii Koshkin visited the students of School No. 124, whose classes are held in a specially equipped underground school in the Saltivskyi district. They conducted a mathematical master class, “Battle of the Fishermen,” for the schoolchildren. The format of the interactive game proved to be highly successful and aroused genuine interest, with most of the children eagerly engaging in the process as both active participants and attentive listeners.

Kharkiv National University of Radio Electronics invites students, PhD students, and young scientists to participate in the 30th International Forum of Young Scientists “Radio Electronics and Youth in the XXI Century”, which will be held on April 22–24, 2026.

Within the framework of the forum, the Department of Applied Mathematics will host Section “7.2. System Analysis, Mathematical and Computer Modeling” as part of the Conference “7. Computer Vision, System Analysis and Mathematical Modeling”. Section Head: Head of the Applied Mathematics Department, Dr. Sc. (Phys.-Math.), Prof. M.V. Sidorov, secretary: Associate Professor of the Applied Mathematics Department, Ph.D. (Phys.-Math.), Assoc. Prof. S.M. Lamtiuhova

In December 2025, the Department of Applied Mathematics of the Kharkiv National University of Radio Electronics, in accordance with NURE Order No. 450 dated November 26, 2025, held the All-Ukrainian Competition of Student Scientific Works “Applied Mathematics and Mathematical Methods of System Analysis”. In total, 21 works were submitted to the competition by students representing leading higher education institutions of Ukraine:

• Vinnytsia National Technical University;
• Dnipro State Technical University;
• Donbas State Engineering Academy;
• Kyiv National Economic University named after Vadym Hetman;
• National Technical University “Kharkiv Polytechnic Institute”;
• National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute”;
• V. N. Karazin Kharkiv National University;
• Kharkiv National University of Radio Electronics;
• Yuriy Fedkovych Chernivtsi National University.

The participants’ works were evaluated by a competition commission consisting of:

As mathematicians, we know that numbers have character. And the year 2026 is special — it is a “happy number”!

In number theory, a happy number is a number that eventually reaches 1 when replaced by the sum of the squares of its digits.
