Researchers Assess Student Performance in Mathematics, Physics, and Critical Thinking
A group of researchers representing four countries summed up the results of the Supertest, a large-scale study of the academic performance of engineering students in Russia, China, India, and the United States. It is the first study to track the progress of students in computer science and electrical engineering over the course of their studies with regard to their abilities in physics, mathematics, and critical thinking and compare the results among four countries. The article about study was published in Nature Human Behavior.

Children's Adaptation to Online Learning Depends on the Nature of Their Parents’ Work
Specialists at the HSE Institute of Education found that the willingness of children to work independently at home during distance learning depended not only on the availability of appropriate technical means in the family (its socio-economic profile), but also on the nature of their parents’ work (a socio-psychological factor).

Father’s Level of Education Affects Students’ Plans for Doctoral Studies
Saule Bekova, Research Fellow at the Centre of Sociology of Higher Education, and Ivan Smirnov, Leading Research Fellow at the Laboratory of Computational Social Sciences, studied how father’s level of education affects students’ plans to receive a doctoral degree. The article Determinants of doctoral degree aspirations: insights from a nationally representative panel study was published in HERB: Higher Education in Russia and Beyond journal.

Generic algebras: rational parametrization and normal forms
Vladimir L. Popov. arxiv.org. math. Cornell University, 2014. No. 1411.6570.
For every algebraically closed field $\boldsymbol k$ of characteristic different from $2$, we prove the following:   (1) Generic finite dimensional (not necessarily associative) $\boldsymbol k$-algebras of a fixed dimension, considered up to isomorphism, are parametrized by the values of a tuple of algebraically independent over $\boldsymbol k$ rational functions in the structure constants.   (2) There exists an "algebraic normal form", to which the set of structure constants of every such algebra can be uniquely transformed by means of passing to its new basis, namely: there are two finite systems of nonconstant polynomials on the space of structure constants, $\{f_i\}_{i\in I}$ and $\{b_j\}_{j\in J}$, such that the ideal generated by the set $\{f_i\}_{i\in I}$ is prime and, for every tuple $c$ of structure constants satisfying the property $b_j(c)\neq 0$ for all $j\in J$, there exists a unique new basis of this algebra in which the tuple $c'$ of its structure constants satisfies the property $f_i(c')=0$ for all $i\in I$.

Quantum toroidal gl(1)-algebra: Plane partitions
Feigin B. L., Jimbo M., Miwa T. et al. Kyoto Journal of Mathematics. 2012. Vol. 52. No. 3. P. 621-659.

In this, the third paper of the series, we construct a large family of representations of the quantum toroidal gl(1)-algebra whose bases are parameterized by plane partitions with various boundary conditions and restrictions. We study the corresponding formal characters. As an application We obtain a Gelfand-Zetlin-type basis for a class of irreducible lowest weight gl(infinity)-modules.

On-line Teaching of Calculus Using WebMathematica
Vorob'ev E. M. In bk.: Globalization: Business, Finance and Education. First International Conference. Sofia: Perun-Sprint Ltd., 2012. Ch. 6.5. P. 566-577.

The paper addresses the on-line teaching of Calculus using webMathematica interactive electronic tutorials developed by the author. The tutorials are available on the web site http://wm.iedu.ru. It is obvious that e-learning technologies need new pedagogy. It is usually called e-pedagogy. We share and realize the main pedagogical principle of webMathematica based learning. The principle is laid out as follows. To teach mathematics not calculation or math not equal calculating.

Bounded limit cycles of polynomial foliations of ℂP²
Goncharuk N. B., Kudryashov Y. arxiv.org. math. Cornell University, 2015. No. 1504.03313.
In this article we prove in a new way that a generic polynomial vector field in ℂ² possesses countably many homologically independent limit cycles. The new proof needs no estimates on integrals, provides thinner exceptional set for quadratic vector fields, and provides limit cycles that stay in a bounded domain.

О топологической устойчивости непрерывных функций в некоторых пространствах, связанных с рядами Фурье
В. В. Лебедев Известия РАН. Серия математическая. 2010. Т. 74. № 2. С. 131-164.

We consider certain spaces of functions on the circle, which naturally appear in harmonic analysis, and superposition operators on these spaces. We study the following question: which functions  have the property that each their superposition with a homeomorphism of the circle belongs to a given space? We also study the multidimensional case.

Оценки в теоремах типа теоремы Берлинга-Хелсона. Многомерный случай
В. В. Лебедев Математические заметки. 2011. Т. 90. № 3. С. 394-407.

We consider the spaces of functions on the m-dimensional torus, whose Fourier transform is p -summable. We obtain estimates for the norms of the exponential functions deformed by a C1 -smooth phase. The results generalize  to the multidimensional case the one-dimensional results obtained by the author earlier in “Quantitative estimates in the Beurling—Helson theorem”, Sbornik: Mathematics, 201:12 (2010), 1811 – 1836.

Short lists with short programs in short time
Bauwens B., Makhlin A., Vereshchagin N. et al. Electronic Colloquium on Computational Complexity. Technical report. Hasso-Plattner-Institut, 2013. No. TR13-007.
Given a machine $U$, a $c$-short program for $x$ is a string $p$ such that $U(p)=x$ and the length of $p$ is bounded by $c$ + (the length of a shortest program for $x$). We show that for any universal  machine, it is possible to compute  in polynomial time  on input $x$ a  list of polynomial size guaranteed to contain a $O(\log |x|)$-short program  for $x$. We also show that there exist computable functions that map every $x$ to a list of size $O(|x|^2)$ containing a $O(1)$-short program for $x$ and this is essentially optimal  because we prove that such a list must have  size  $\Omega(|x|^2)$. Finally we show that for some machines, computable  lists containing a shortest  program must have length $\Omega(2^{|x|})$.

Laminations from the Main Cubioid
Timorin V., Blokh A., Oversteegen L. et al. arxiv.org. math. Cornell University, 2013. No. 1305.5788.
According to a recent paper \cite{bopt13}, polynomials from the closure $\ol{\phd}_3$ of the {\em Principal Hyperbolic Domain} ${\rm PHD}_3$ of the cubic connectedness locus have a few specific properties. The family $\cu$ of all polynomials with these properties is called the \emph{Main Cubioid}. In this paper we describe the set $\cu^c$ of laminations which can be associated to polynomials from $\cu$.

Conjugacy classes in discrete Heisenberg groups
Roman Budylin. arxiv.org. math. Cornell University, 2014
We study some extension of a discrete Heisenberg group coming from the theory of loop-groups and find invariants of conjugacy classes in this group. In some cases including the case of the integer Heisenberg group we make these invariants more explicit.
