# Math in Moscow

For the second year running Igor Artamkin, tenured professor, deputy head of the Faculty of Mathematics at HSE, has been named 'Best Teacher of the University'.

Right from the start when the faculty was set up in 2008, he with a team of likeminded people created conditions for study in the spirit of the unique principles of the Moscow school. This is an approach based on students solving problems independently and discussing their answers with their teachers in person. This is not a test but rather the central process of learning. This is how a taste for math is passed on from teacher to student, a sense of the depth and beauty of solutions and a large part of mathematical study. This kind of individual work of the teacher with his/her student is similar to traditional approaches in the creative arts.

Students get involved in academic work right from the start. They take part all the time in courses and seminars about the most recent mathematical discoveries with the people who made them. So students are getting information directly from the source and have the chance to ask questions and get answers from the most qualified specialists. The faculty also runs intensive mini-courses on various subjects.

Igor Artamkin has designed and combined teaching plans and course timetables to the best effect and has set out a system of registering the students’ achievements. Students and teachers spend their time at the faculty most efficiently. The deputy head is always aware of any problems his students are having and ready to help them.

Creating the English Master’s programme and integrating the faculty with 'Math in Moscow' which is run for foreign students is another of Igor Artamkin’s significant personal achievements.

## Immortal Cells and Mathematics Reveal Mechanism behind Coronavirus Infection

A mathematical model has helped describe the course of infection caused by two variants of coronavirus: Omicron and Delta, and explain the differences between them. It appears that the cell entry rate is lower for Omicron, allowing infected cells ample time to alert neighbouring cells of the threat and trigger the activation of their innate immune response. In the future, the developed model could be employed to investigate any other variant of COVID-19, potentially leading to effective strategies for combating new hazardous strains, such as Pirola and JN.1. The findings from the study conducted with the participation of HSE researchers have been published in PeerJ.

## Mathematicians Reveal the Mechanism behind Neuron Synchronisation: Hyperchaos

Scientists of the International Laboratory of Dynamic Systems and Applications at HSE Campus in Nizhny Novgorod have described a rare case of synchronisation in a system of chemically coupled neuron models. The study findings enable a mathematical description of atypical brain functioning modes, including those associated with neurodegenerative diseases. The study has been published in Regular and Chaotic Dynamics.

## ‘The Joy of Science Lies in the Euphoria of Learning’

For Elena Nozdrinova, mathematics is her life's work and a realm where she discovers universal order and harmony. In her interview with the HSE Young Scientists project, she speaks about dynamical systems, the Nizhny Novgorod scientific school, and favourite pastimes that help her grow.

## HSE Scientists Unveil New Findings Regarding Stability of Communication Systems

Researchers from the International Laboratory of Dynamical Systems and Applications at the HSE Campus in Nizhny Novgorod have discovered that the use of systems with hyperbolic solenoid attractors and repellers can lead to issues in the transmission of communication signals. The findings of this study have been published in Results in Mathematics. The research was financed by a substantial grant from the Russian Government as part of the 'Science and Universities' National Project and a further grant from the Russian Science Foundation.

## Monsters of the Deep: HSE Scientists Have Compiled a Catalogue of Rogue Waves

Rogue waves, or killer waves, are abnormally high and deadly waves that can emerge unpredictably in open seas and along shorelines. They pose an imminent deadly threat to everyone from colossal liners and pleasure yachts to seafarers and vacationers. Scientists from the HSE campus in Nizhny Novgorod Efim Pelinovsky and Ekaterina Didenkulova have assembled a catalogue of such phenomena that occurred in the World Ocean from 2011 to 2018, identifying the areas where they are frequently documented and inflict the most substantial damage.

## Students of Engineering and Mathematics School Present First Project Results

Students of the Engineering and Mathematics School (EMS) launched by HSE University and VK in October 2022 held a Demo Day to showcase the first results of their product- and research-based IT projects. Work on the projects has been conducted under the supervision of experts from the university and mentors from VK.

## ‘I Prefer Work to Most Types of Pastime’

Ivan Arzhantsev has headed up the Faculty of Computer Science since it was established in 2014. He has never been a specialist in Computer Science – all his life he’s been engaged in mathematics. On his 50th birthday, he shared with HSE Life how this has helped him to lead the best HSE faculty.

## HSE University Students Win Prizes at the International Mathematics Competition for University Students

The 29th International Mathematics Competition for University Students (IMC 2022) took place in early August in a mixed format in Blagoevgrad (Bulgaria) and online. Eight students of the HSE Faculty of Computer Science and the HSE Faculty of Mathematics won prizes at the competition.

## ‘HSE University Was a Gateway into the Wider World of Science’

Fernanda Florido-Calvo came to HSE University in Nizhny Novgorod from Chile to study mathematics. While on her two-year Master of Science in Mathematics programme, she wrote her master’s thesis and presented it at the All-Russia Contest of Diploma Thesis of Russian Mathematicians 2021, where she won two awards with full marks. Fernanda spoke to the HSE News Service about her passion for mathematics and the paths that lead to HSE University.

## HSE University Researchers to Speak at the International Congress of Mathematicians

The speakers of the International Congress of Mathematicians, a key global mathematics event held every four years by the International Mathematical Union, have been announced. The next ICM will take place in St. Petersburg, Russia, in July 2022. Five researchers from the HSE Faculty of Mathematics will present their papers at the congress.
