10 tasks, 2 days and 3 medals. Students of the Faculty of Physics, Mathematics and Natural Sciences of RUDN University took part in the International Mathematics Competition for University Students in Blagoevgrad, Bulgaria and returned with silver and two bronze awards.
The competition took place from July 28 to August 3 and brought together more than 430 undergraduate students (aged 23 and under) from over 50 leading universities around the world. The students solved problems from various areas of mathematics: linear algebra, mathematical analysis, number theory, and probability theory.
Set of numbers
Serafim Vinogradsky is participating in the IMC Olympiad for the fourth time. According to the student, the tasks this year seemed a little easier to him than last year. But he noted that this is only his personal feeling.
"The structure of the Olympiad is such that on each of the two days we had to solve five problems in five hours, each problem was worth a maximum of 10 points. Moreover, the first two problems are the easiest, since according to the logic of the organizers, most of the participants in the competition should be able to cope with them. And the last two problems, of course, are the most difficult. I was not able to solve them, but the points I scored for other problems allowed me to win silver," – Serafim Vinogradsky, bachelor of the Faculty of Philosophy, Mathematics, RUDN University (mathematics, 4th year).
Egor Smirnov-Maltsev and Leonid Finarevsky became bronze medalists of the Olympiad. The guys are also not newcomers to mathematical competitions of various levels.
"If we talk about a problem with one of the simplest conditions, it sounded like this: "Find all sets consisting of pairwise distinct natural numbers, where for each set M the following is true: 1) If a number x is in a set M, and a number 2x is in this set; 2) If x and y are in a set M and xy is even, then (xy)/2 is in this set. I was able to cope with problems 1–3 on the first day, but on the second day the tasks were already very difficult," — Leonid Finarevsky, Faculty of Physics, Mathematics and Natural Sciences, RUDN (Applied Mathematics and Computer Science, 4th year).
International friendship and nostalgia
To help students unwind and take a break from intense mental work, the Olympiad organizers arranged an excursion to the Rila Monastery. It was founded at the end of the 10th century and is located in the mountains at an altitude of 1,147 m above sea level. The UNESCO-protected landmark has beautiful architecture with many white colonnades and incredibly detailed wall paintings.
"And next to the monastery there was a beautiful forest and a river, in which we even had a chance to swim. As for the walks around Blagoevgrad, for me they turned out to be nostalgic, because I was not coming here for the first time," – Seraphim Vinogradsky.
Leonid noted that in Bulgaria their team was able to communicate with old acquaintances – students from Turkmenistan. The RUDN students regularly meet with the guys at international competitions. Including at the RUDN Math Olympiad and OMOUS-2025, which is held in the homeland of their friends.
"Among the new acquaintances were participants from Belarus and Cyprus. In general, this trip was memorable because we managed to walk around Blagoevgrad more, communicate more. The city has a cozy atmosphere, it is surrounded by mountains, and it is located in a river valley. It is calm and very beautiful here," Leonid Finarevsky.
