Research & Expertise News at HSE University

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).

The AI and Digital Science Institute at the HSE Faculty of Computer Science hosted a conference focused on cutting-edge recommender system technologies. In an atmosphere of active knowledge sharing among leading industry experts, participants were introduced to the latest advancements and practical solutions in recommender model development.

Georgy Stalinov conducts field-based social research and has created a video podcast about unusual social phenomena based on fieldwork materials. In an interview with the HSE Young Scientists project, he spoke about hitchhiking with lorry drivers, why working as a taxi driver can be a bad idea, and whether poaching exists in Kamchatka.

Experts from HSE University took part in the BRICS Academic Forum (FABRICS) held in the capital of Brazil this year. The main theme of the event was to discuss cooperation among countries in the Global South amid geopolitical turbulence and rapid technological change. Academics and experts from BRICS member states and partner nations explored topics such as global healthcare, AI technologies, trade, climate change, and reform of the multilateral global security and governance architecture.

The rapid growth of India’s economy and its predominantly young population present unprecedented opportunities for Russian businesses. However, success in this vast market requires a deep understanding of its internal diversity, as well as cultural and legal nuances. These issues were the focus of the business session ‘India: A Market of a Billion Chances. How to Succeed,’ organised by the expert club of the Eastern Perspective programme at the HSE Faculty of World Economy and International Affairs.

An international research team surveyed over 10,000 respondents across 43 countries to examine how closely the ideal image of a romantic partner aligns with the actual partners people choose, and how this alignment shapes their romantic satisfaction. Based on the survey, the researchers compiled two ratings—qualities of an ideal life partner and the most valued traits in actual partners. The results have been published in the Journal of Personality and Social Psychology.

The rapid development of technology, the adaptation of business processes to new economic realities, and changing audience demands require professionals in the creative industries to keep up with current trends and be flexible in their approach to projects. Between April and May 2025, the Institute for Creative Industries Development (ICID) at the HSE Faculty of Creative Industries conducted a trend study within the creative sector.

HSE University hosted a roundtable titled ‘New Challenges for Antitrust Regulation: The Chinese Perspective.’ The event was organised by the International BRICS Competition Law and Policy Centre (BRICS Centre). Special guests included Chinese colleagues from the Competition Policy and Assessment Centre (CPAC) of the State Administration for Market Regulation of the People’s Republic of China (SAMR). Last year, the BRICS Centre and CPAC SAMR signed an agreement on strategic cooperation.
