Locally finite groups with bounded centralizer chains
Alexandr Buturlakin, Andrey V. Vasil'ev
The c-dimension of a group G is the maximal length of a chain of nested centralizers in G. We prove that a locally finite group of finite c-dimension k has less than 5k nonabelian…
A two-type Bellman--Harris process initiated by a large number of particles
Vladimir Vatutin, Alexander Iksanov, Valentin Topchii
We investigate a two-type critical Bellman--Harris branching process with the following properties: the tail of the life-length distribution of the first type particles is of order…
Aperiodic pseudorandom number generators based on infinite words
Lubomira Balkova, Michelangelo Bucci, Alessandro De Luca +2
In this paper we study how certain families of aperiodic infinite words can be used to produce aperiodic pseudorandom number generators (PRNGs) with good statistical behavior. We i…
Full-Rank Perfect Codes over Finite Fields
Alexander M. Romanov
In this paper, we propose a construction of full-rank q-ary 1-perfect codes over finite fields. This construction is a generalization of the Etzion and Vardy construction of full-r…
On non-abelian Schur groups
Ilya Ponomarenko, Andrey Vasil'ev
A finite group G is called Schur, if every Schur ring over G is associated in a natural way with a regular subgroup of Sym(G) that is isomorphic to G. We prove that any nonabelian…
Nonsoluble and non-p-soluble length of finite groups
E. I. Khukhro, P. Shumyatsky
Every finite group has a normal series each of whose factors either is soluble or is a direct product of nonabelian simple groups. We define the nonsoluble length as the…
How learn the branching ratio X(3872)\to D^{*0}\bar D^0 + c.c
N. N. Achasov, E. V. Rogozina
Enfant terrible of charmonium spectroscopy, the resonance , generated a stream of interpretations and ushered in a new exotic spectroscopy. In th meantime, many (if…
Abelian symmetries of the N-Higgs-doublet model with Yukawa interactions
I. P. Ivanov, C. C. Nishi
We investigate finite abelian groups which can represent symmetries of the N-Higgs-doublet models with quarks. We build a general formalism based on the powerful method of the Smit…
Turan Problems and Shadows I: Paths and Cycles
Alexandr Kostochka, Dhruv Mubayi, Jacques Verstraëte
A -path is a hypergraph P_k = e_1,e_2,...,e_k such that |e_i \cap e_j| = 1 if |j - i| = 1 and e_i \cap e_j is empty otherwise. A k-cycle is a hypergraph C_k = e_1,e_2,.. ,e_k ob…
The Jacobian Conjecture, together with Specht and Burnside-type problems
Alexei Belov, Leonid Bokut, Louis Rowen +1
We explore an (unpublished) approach to the famous Jacobian Conjecture by means of identities of algebras, discovered by the brilliant deceased mathematician, Alexander Vladimirovi…
Two-dimensional von Neumann--Wigner potentials with a multiple positive eigenvalue
R. G. Novikov, I. A. Taimanov, S. P. Tsarev
By the Moutard transformation method we construct two-dimensional Schrodinger operators with real smooth potential decaying at infinity and with a multiple positive eigenvalue. The…
Comparative study of the production of scalar and tensor mesons in collisions
N. N. Achasov, A. I. Goncharenko, A. V. Kiselev +1
The intensity of scalar , and tensor , mesons production at VEPP-2000 (BINP, Novosibirsk) and the upgraded DANE (Frascati, Italy) in…
Semi-isolation and the strict order property
Sergey Sudoplatov, Predrag Tanović
We study semi-isolation as a binary relation on the locus of a complete type and prove that under some additional assumptions it induces the strict order property.
Towards harmonic superfield formulation of , SYM theory with the central charge
I. L. Buchbinder, N. G. Pletnev
We develop a superfield formulation of supersymmetric Yang-Mills theory with gauged central charge in harmonic superspace. Component formulation of this th…
Asymptotic Expansion of Gaussian Chaos via Probabilistic Approach
Enkelejd Hashorva, Dmitry Korshunov, Vladimir I. Piterbarg
For a centered -dimensional Gaussian random vector and a homogeneous function we derive asymptotic expansions for the tail of the Gaussian chao…
Nonstandard Analysis: Its Creator and Place
S. S. Kutateladze
This is a biographical sketch and tribute to Abraham Robinson (1918-1974) on the 95th anniversary of his birth with a short discussion of the place of nonstandard analysis in the p…
Planar 4-critical graphs with four triangles
Oleg V. Borodin, Zdeněk Dvořák, Alexandr V. Kostochka +2
By the Grunbaum-Aksenov Theorem (extending Grotzsch's Theorem) every planar graph with at most three triangles is 3-colorable. However, there are infinitely many planar 4-critical…
Influence of vacuum electric field on the stability of a plasma-vacuum interface
Nikita Mandrik, Yuri Trakhinin
We study the free boundary problem for the plasma-vacuum interface in ideal compressible magnetohydrodynamics. Unlike the classical statement, when the vacuum magnetic field obeys…
Polarization radiation of vortex electrons with large orbital angular momentum
Igor P. Ivanov, Dmitry V. Karlovets
Vortex electrons, - freely propagating electrons whose wavefunction has helical wavefronts, - could become a novel tool in the physics of electromagnetic radiation. They carry a no…
Pion form factor and reactions e^+e^---> omega pi^0 and e^+e^---> pi^+ pi^- pi^+ pi^- at energies up to 2-3 GeV in the many-channel approach
N. N. Achasov, A. A. Kozhevnikov
Using the field-theory-inspired expression for the pion electromagnetic form factor F_π, a good description of the data in the range -10<s<1 GeV^2 is obtained upon taking into acco…

Ilya Peshkov, Miroslav Grmela, Evgeniy Romenski
On the example of two-phase continua experiencing stress induced solid-fluid phase transitions we explore the use of the Euler structure in the formulation of the governing equatio…
Detecting transition radiation from a magnetic moment
Igor P. Ivanov, Dmitry V. Karlovets
Electromagnetic radiation can be emitted not only by particle charges but also by magnetic moments and higher electric and magnetic multipoles. However experimental proofs of this…
