On quantum -Toda chain
A. A. Gerasimov, D. R. Lebedev, S. V. Oblezin
The orthosymplectic super Lie algebra is the closest analog of standard Lie algebras in the world of super Lie algebras. We demonstrate that the corresp…
A Catalog of Bipolar Active Regions Violating the Hale Polarity Law, 1989-2018
A. Zhukova, A. Khlystova, V. Abramenko +1
There is no list of bipolar active regions (ARs) with reverse polarity (anti-Hale regions), although statistical investigations of such ARs (bearing the imprint of deep subphotosph…
Model reduction in Smoluchowski-type equations
Ivan V. Timokhin, Sergey A. Matveev, Eugene E. Tyrtyshnikov +1
In this paper we utilize the Proper Orthogonal Decomposition (POD) method for model order reduction in application to Smoluchowski aggregation equations with source and sink terms.…
Commutator length of powers in free products of groups
Vadim Yu. Bereznyuk, Anton A. Klyachko
Given groups and , what is the minimal commutator length of the 2020th (for instance) power of an element not conjugate to elements of the free factors? The exhau…
Hidden toric symmetry and structural stability of singularities in integrable systems
Elena A. Kudryavtseva
The goal of the paper is to develop a systematic approach to the study of (perhaps degenerate) singularities of integrable systems and their structural stability. As the main tool,…
Shape of solar cycles and mid-term solar activity oscillations
D. D. Sokoloff, A. S. Shibalova, V. N. Obridko +1
The evolution of the solar activity comprises, apart from the well-known 11-year cycle, various temporal scales ranging from months up to the secondary cycles known as mid-term osc…
Wavelet analysis of the long-term activity of V833 Tau
R. Stepanov, N. I. Bondar', M. M. Katsova +2
The bulk of available stellar activity observations is frequently checked for the manifestation of signs in comparison with the known characteristic of solar magnetic modulation. T…
Matching the heavy-quark fields in QCD and HQET at four loops
Andrey G. Grozin, Peter Marquard, Alexander V. Smirnov +2
The QCD/HQET matching coefficient for the heavy-quark field is calculated up to four loops. It must be finite; this requirement produces analytical results for some terms in the fo…
