Preserving Rationality in a Period of Turbulence
The HSE International Laboratory for Logic, Linguistics and Formal Philosophy studies logic and rationality in a transformed world characterised by a diversity of logical systems and rational agents. The laboratory supports and develops academic ties with Russian and international partners. The HSE News Service spoke with the head of the laboratory, Prof. Elena Dragalina-Chernaya, about its work.

‘All My Time Is Devoted to My Dissertation
Ilya Venediktov graduated from the Master’s programme at the HSE Tikhonov Moscow Institute of Electronics and Mathematics through the combined Master’s–PhD track and is currently studying at the HSE Doctoral School of Engineering Sciences. At present, he is undertaking a long-term research internship at the University of Science and Technology of China in Hefei, where he is preparing his dissertation. In this interview, he explains how an internship differs from an academic mobility programme, discusses his research topic, and describes the daily life of a Russian doctoral student in China.

Новые двусторонние оценки полных эллиптических интегралов первого и второго рода

Огарёв-Online. 2021. № 12. Статья 3.
Алексеева Е. С., Рассадин А. Э.

Two theorems are proved in this paper, in which lower and upper bounds are established for complete elliptic integrals of the first and second kind, expressed in terms of elementary functions. These theorems are applied to a model geometric example. In addition, the article presents graphs of dependencies on the modulus of these integrals of both the estimates obtained and their relative errors. The applicability of the approximations found for technical applications is also discussed.

Bifurcations and Structural Stability of Generic PC-HC Families
Dorovskiy A., / Series arXiv "math". 2026.
In this paper the structural stability of generic families of vector fields of the PC-HC class on the two-dimensional sphere is proved. A classification of these families up to moderate equivalence in neighborhoods of their large bifurcation supports is presented, based on such invariants as the configuration and the characteristic set. The realization lemma is proved. ...

The Sobolev space W_2^{1/2}: Simultaneous improvement of functions by a homeomorphism of the circle
Lebedev V., Journal of Mathematical Analysis and Applications 2026 Vol. 563 No. 2 Article 130787
It is known that for every continuous real-valued  function $f$ on the circle $\mathbb T=\mathbb R/2\pi\mathbb Z$ there exists a  change of variable, i.e., a self-homeomorphism $h$ of $\mathbb T$, such that  the superposition $f\circ h$ is in the Sobolev space $W_2^{1/2}(\mathbb T)$.  We obtain new results on simultaneous improvement of functions by a single  change of variable in relation ...

We describe a model for the boundary of the connectedness locus of the parameter space of cubic symmetric polynomials. We show that there exists a monotone continuous function from the connectedness locus to the model which is a homeomorphism if the former is locally connected. ...

Игры на сетях с линейным наилучшим ответом: модели и методы управления
Petrov I., Автоматика и телемеханика 2026 № 6 С. 82–118
Системам связанных агентов и сетевому управлению посвящено большое число отечественных и зарубежных исследований. Исторически, наибольший интерес в теории управления возникал к усредняющим системам и, в частности, к задаче консенсуса. Однако сетевое взаимодействие может характеризоваться более специфическими функциями, отражающими зависимость от действий соседей по сети, что особенно явно проявляется в моделях стратегического взаимодействия на сети, которое ...

A two-point phase recovering from holographic data on a single plane
Novikov R., Sivkin V., Inverse Problems 2026 Vol. 42 No. 4 Article 045009
We consider a plane wave, a radiation solution, and the sum of these solutions (total solution) for the Helmholtz equation in an exterior region in Rd, d ⩾ 2. In this region, we consider a hyperplane X with sufficiently large distance s from the origin in Rd. We give two-point local formulas for approximate recovering the radiation ...

Multivariate Newton interpolation in downward closed spaces reaches the optimal Bernstein–Walsh approximation rate
Hecht M., Hofmann P., Wicaksono D. et al., IMA Journal of Numerical Analysis 2026 Vol. 00 P. 1–30
Recent advances in Bernstein—Walsh theory have extended Bernstein’s Theorem to multiple dimensions, stating that a multivariate function can be approximated with a geometric rate in a downward-closed polynomial space if and only if it is analytic in a generalized Bernstein polyellipse. To compute approximations of this class of functions—which we term Bos–Levenberg–Trefethen–(BLT) functions—we extend the ...

Weighted Chernoff Information and Optimal Loss Exponent in Context-Sensitive Hypothesis Testing
Kelbert M., Kalimulina E. Y., Entropy 2026 Vol. 28 Article 536
We study binary hypothesis testing for i.i.d. observations under a multiplicative context weight. For the optimal weighted total loss, defined as the sum of weighted type-I and typeII losses, we prove the logarithmic asymptotic L∗n = exp{−nDwC (P,Q) + o(n)}, n →∞, where Dw C is the weighted Chernoff information. The single-letter form of the exponent relies on ...

We prove equivalence of two integral representations for the wave functions of hyperbolic Calogero–Sutherland system. For this we study two families of Baxter operators related to hyperbolic Calogero–Sutherland and rational Ruijsenaars models; the first one as a limit from hyperbolic Ruijsenaars system, while the second one independently. Besides, computing asymptotics of integral representations and also ...

Hodge Laplacian Eigenvalues on Surfaces with Boundary

Recently Rohleder proposed a new variational approach to an inequality between the Neumann and Dirichlet eigenvalues in the simply connected planar case using the language of classical vector analysis. Interpreting his approach in terms of differential forms permits to generalize these results to a much broader context. The spectrum of the absolute boundary problem for ...

On Undecidability Degree of Theory of Figures in Countable and Uncountable Linear Spaces
Dudakov S., Lobachevskii Journal of Mathematics 2025 Vol. 46 No. 12 P. 6092–6102
We study the additive theory of arbitrary figures in linear spaces, that is, the theory of addition extended to sets of vectors. Our main result is the following: if a linear space is infinite, then the additive theory of figures admits interpreting second-order arithmetic and, therefore, it has such or higher degree of undecidability. For countably infinite spaces, ...

On the minimum number of maximal distance-k independent sets in trees
Taletskii D., / Series arXiv "math". 2026.
A vertex subset of a graph is called a \textit{distance-$k$ independent set} if the distance between any two of its distinct vertices is at least $k + 1$. For all $n,k \geq 1$, we determine the minimum possible number of inclusion-wise maximal distance-$k$ independent sets among all $n$-vertex trees. It equals~$n$ if $n \leq k ...

В статье показано, что базовые свойства некоторых моделей монополистической конкуренции описываются с помощью семейств гипергеометрических функций. Результаты получены построением модели общего равновесия в многосекторной экономике, производящей дифференцированное благо в n высокотехнологичных секторах, в которых однопродуктовые фирмы конкурируют монополистически, используя одинаковые технологии. Однородный (традиционный) сектор характеризуется совершенной конкуренцией. Работники мотивированы найти работу в высо- котехнологичных секторах, ...

The construction is based on conditional maximization, which permits us to introduce the conjugate variables and the Lagrangian manifold corresponding to the semigroup (G, ∂). ...
