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.

The year 2025 was marked by significant events in mathematics — from international recognition of scholars to historic breakthroughs in fundamental theories.

Outstanding Awards and Recognition

Breakthrough Prize in Mathematics — the prestigious 2025 prize was awarded to the eminent mathematician Dennis Gaitsgory for his fundamental contributions to the Geometric Langlands Program, in particular for proving the Geometric Langlands Conjecture in characteristic zero.
