Immunity to Chaos: How Personal Resources Help Us Cope with the Challenges of a Turbulent World
International conflicts, crises and digital overload—the modern world puts our minds to the test every day. Traditional psychology often focuses on the consequences: anxiety, depression, and psychosomatic disorders. But what if we looked at the problem differently—through the lens of the resources that prevent us from breaking down? Psychological immunity is precisely this set of resources. Alena Zolotareva and her group, Psychological Immunity as a Resource for Positive Functioning, are developing an integrative model of this phenomenon, adapting diagnostic tools and preparing for large-scale empirical research. Why do psychologists need to collaborate with medical professionals, and how could their research transform preventive care in clinics and corporations?

How to Assess Students Knowledge in the Age of AI
A researcher at HSE University has proposed a flowchart to help lecturers decide how to assess students who use artificial intelligence. It shows where the use of AI should be restricted and where it can be incorporated into the learning process. The article has been published in IT Professional.

‘Balkan Hospitality Opens Doors: Studying Dialects on the Verge of Extinction
You cannot study spoken dialects from books. Instead, you need to go to a village, seek out its elders, and earn the trust of local residents before you can record hours of spontaneous stories. This is how Natalia Muravleva, Associate Professor at the Faculty of Humanities, conducts her research. Her internship in Serbia continued her long-standing study of dialects spoken by Macedonian settlers. In this interview, she discusses how diaspora cultural centres help researchers reach informants, why native speakers need to be interviewed only in their own language (otherwise, as she puts it, they may 'break'), and how a single field season helped her finalise her monograph. She also shares warm memories of autumn in Belgrade and of colleagues with whom grammar can be discussed in three languages at once.

Кольца коэффициентов формальных групп
Buchstaber V. M., Ustinov A., Математический сборник 2015 Т. 206 № 11 С. 19–60
We describe the coefficient rings of universal formal group laws which arise in algebraic geometry, algebraic topology and their application to mathematical physics. We also describe the homomorphisms of these coefficient rings coming from reductions of one formal group law to another. The proofs are based on the number-theoretic properties of binomial coefficients. ...

Кольца коэффициентов формальных групп Тейта, задающих роды Кричевера
Ustinov A., Buchstaber V. M., Бунькова Е. Ю., Труды Математического института им. В.А. Стеклова РАН 2016 Т. 292 С. 43–68
The paper is devoted to problems at the intersection of formal group theory, the theory of Hirzebruch genera, and the theory of elliptic functions. In the focus of our interest are Tate formal groups corresponding to the general five-parametric model of the elliptic curve as well as formal groups corresponding to the general four-parametric Krichever ...

Формальная группа Бухштабера и эллиптические функции малых уровней
Ustinov A., Математические заметки 2017 Т. 102 № 1 С. 96–108
In the paper, we suggest a method for finding relations concerning series defining the Buchstaber formal group. This method is applied to the cases in which the exponent of the group is an elliptic function of level n=2,3, and 4. An algebraic relation for the series defining the universal Buchstaber formal group is also proved. ...

Точность по Ландвеберу формальной группы c1-сферических бордизмов
Черных Г. С., Математические заметки 2023 Т. 113 № 6 С. 918–928
We describe the structure of the coefficient ring W(pt)=Ω^W of the c_1-spherical bordism theory for an arbitrary SU-bilinear multiplication. We prove that for any SU-bilinear multiplication the formal group of the theory W∗ is Landweber exact. Also we show that after inverting the set P of Fermat primes there exists a complex orientation of the localized theory W[P^(−1)] such that the coefficients of the corresponding formal ...

Вычисление гиперэллиптических систем последовательностей ранга 4
Illarionov A., Известия РАН. Серия математическая 2023 Т. 87 № 6 С. 76–102
Выводятся формулы для последовательностей комплексных чисел, удовлетворяющие функциональным соотношениям билинейного типа. Полученные результаты используются для описания всех целых 1-периодических функций $f,g: C→C$, удовлетворяющих вместе с некоторыми $ϕ_j,ψ_j:C\to C$ разложению $f(x+y)g(x−y)=ϕ_1(x)ψ_1(y)+⋯+ϕ_4(x)ψ_4(y)$. ...

A General Harmonic Solution in Dilaton Electrodynamics: An Exact Expression for the Fields and the Generalized Lorentz Force
Mosharev P., Кечкин О. В., Moscow University Physics Bulletin 2020 Vol. 75 No. 5 P. 427–433
An exact expression is obtained for harmonic fields in Maxwell electrodynamics with dilatons in terms of elliptic Jacobi functions and elliptic Legendre integrals. The case of centrally symmetric fields is considered individually and effective charges of all three types, that is, electric, magnetic, and dilaton charges, are calculated. An expression is given for the generalized ...

Semenov-Tian-Shansky K. M., Поляков М. В., Смирнов А. О. et al., Теоретическая и математическая физика 2019 Т. 200 № 2 С. 290–309
Leading logarithms in massless nonrenormalizable effective field theories can be computed using nonlinear recurrence relations. These recurrence relations follow from the fundamental requirements of unitarity, analyticity, and crossing symmetry of scattering amplitudes and generalize the renormalization group technique to the case of nonrenormalizable effective field theories. We review the existing exact solutions of nonlinear recurrence relations relevant for field ...
