HSE — Nizhny Novgorod

Mathematician Ivan Remizov from HSE University–Nizhny Novgorod and the Institute for Information Transmission Problems of the Russian Academy of Sciences has made a conceptual breakthrough in the theory of differential equations. He has derived a universal formula for solving problems that had been considered unsolvable in quadratures for more than 190 years. This result fundamentally reshapes one of the oldest areas of mathematics and has potential to have important implications for fundamental physics and economics. The paper has been published in Vladikavkaz Mathematical Journal.

This was the second hackathon organised by the Analytical Centre of Nizhny Novgorod and the city’s Digital Transformation Department. Eighteen student teams from the city's major higher education institutions participated, spending 52 hours developing innovative, AI-powered digital products designed to benefit Nizhny Novgorod and its residents.

In September 2025, Nizhny Novgorod became the centre of the international youth movement, hosting around 2,000 participants from 120 regions of Russia and abroad at the World Youth Festival Assembly. Students of HSE University–Nizhny Novgorod’s Foreign Languages and Intercultural Business Communication, Fundamental and Applied Linguistics, and International Bachelor’s in Business and Economics programmes were involved in the event in a variety of roles, from attachés and volunteers to performers and speakers.

Almost 200 students of IT programmes at HSE University–Nizhny Novgorod will soon be able to live in modern co-living spaces with all the essentials for living, studying, and working. The complex on Bolshie Ovragi Ulitsa boasts 1,359 places and a dedicated ecosystem for fostering the development of future IT specialists.

HSE University in Nizhny Novgorod has hosted Hack Summer, an annual festival for students of the International Bachelor's in Business and Economics. The event helps first-year students learn more about the university and prepare for busy academic life. In addition to the entertainment programme, special attention was paid this year to the development of skills necessary for today’s students.

In 1968, American mathematician Paul Chernoff proposed a theorem that allows for the approximate calculation of operator semigroups, complex but useful mathematical constructions that describe how the states of multiparticle systems change over time. The method is based on a sequence of approximations—steps which make the result increasingly accurate. But until now it was unclear how quickly these steps lead to the result and what exactly influences this speed. This problem has been fully solved for the first time by mathematicians Oleg Galkin and Ivan Remizov from the Nizhny Novgorod campus of HSE University. Their work paves the way for more reliable calculations in various fields of science. The results were published in the Israel Journal of Mathematics (Q1).
