Солитоны в обобщенной квантовой гидродинамике и теория шаровой молнии
No full textQuantum solitons are discovered with the help of generalized quantum hydrodynamics. The solitons have the character of the stable quantum objects in the self consistent electric field. The theory of quantum solitons lead to explanation of the existence of stable atom structures on the microscopic level and lightning balls on the macroscopic level of description of physical systems. The delivered theory demonstrates the great possibilities of the generalized quantum hydrodynamics in investigation of the quantum solitons. The paper can be considered also as comments and prolongation of the materials published in the known author`s monograph (Boris V. Alexeev, Generalized Boltzmann Physical Kinetics. Elsevier. 2004). The theory leads to solitons as typical formations in the generalized quantum hydrodynamics.Квантовые солитоны открыты с помощью обобщенной квантовой гидродинамики. Солитоны имеют характер стабильных квантовых объектов в самосогласованном электрическом поле. Теория квантовых солитонов приводит к объяснению существования стабильных атомов на микроскопическом уровне и шаровых молний на макроскопическом уровне описания физических систем. Разработанная теория демонстрирует большие возможности обобщенной квантовой гидродинамики в исследовании квантовых солитонов как типичных образований в обобщенной квантовой теории. Статья может также рассматриваться как продолжение исследований, изложенных в известной монографии автора (Boris V. Alexeev, Generalized Boltzmann Physical Kinetics. – Elsevier, 2004)
К обобщенной релятивистской кинетической и гидродинамической теории
No full textOn the basis of statistical description the movement of relativistic particles without external forces is considered. The hydrodynamic form of the Dirac equation is suggested. The Lorentz invariant form of the non-local Alexeev equation (generalized Boltzmann equation) was obtained. These results lead to the possibility of construction of relativistic quantum hydrodynamics. This paper can also be considered as continuation of the known monograph (Boris V. Alexeev, Generalized Boltzmann Physical Kinetics. Elsevier. 2004).На основе статистического описания рассматривается движение релятивистских частиц без учета внешних сил. Представлена гидродинамическая форма уравнения Дирака. Получена лоренц-инвариантная форма нелокального кинетического уравнения Алексеева (обобщенного уравнения Больцмана), что открывает возможность построения обобщенной релятивистской квантовой гидродинамики. Статья может также рассматриваться как продолжение исследований, изложенных в известной монографии. (Boris V. Alexeev, Generalized Boltzmann Physical Kinetics. Elsevier. 2004)
Обобщенная квантовая гидродинамика
No full textThis paper addresses the fundamental principles of generalized Boltzmann physical kinetics, as a part of non-local physics. It is shown that the theory of transport processes (including quantum mechanics) can be considered in the frame of unified theory based on the non-local physical description. The paper can be considered also as comments and prolongation of the materials published in the known author’s monograph (Boris V. Alexeev, Generalized Boltzmann Physical Kinetics. Elsevier. 2004).В статье рассматриваются фундаментальные принципы обобщенной Больцмановской физической кинетики как составной части нелокальной физики. Установлено, что теория процессов переноса (включая квантовую механику) может быть рассмотрена в рамках универсальной теории, основанной на нелокальном физическом описании. Статья может рассматриваться как продолжение исследований, опубликованных в известной монографии автора (Boris V. Alexeev, Generalized Boltzmann Physical Kinetics. Elsevier. 2004)

On the existence of ramified abelian covers
No full textGiven a normal complete variety over an algebraically closed field
, distinct effective Weil divisors of and positive
integers , we spell out the conditions for the existence of an
abelian cover of branched with order on .
As an application, we prove that a cover of a normal complete toric variety
branched on the torus-invariant divisors is itself a toric variety if the
characteristic of is equal to 0 or if the cover is Galois of degree
not divisible by the characteristic.Comment: Dedicated to Alberto Conte on his 70th birthday. Version 3: Thm. 3.7
has been reformulated. We thank Boaz Moerman for pointing out that the
earlier version of this result was incorrec

Income Distribution and Price Controls: Targeting a Social Safety Net During Economic Transition
No full textDuring the ongoing post-communist economic transitions, the relative well-being of many people is changing rapidly, and governments are not well positioned to accurately measure individual living standards. Under such circumstances, continued price controls over basic consumer goods within the state sector, and the associated queuing, can form a serviceable device for targeting poor people for subsidies. With a fixed-price state sector and free-price parallel markets, rich people might choose to avoid queues and shop in the free markets, while poor people would prefer to pay low nominal prices and queue in the state sector. The targeting of subsidies through queues, therefore, can be accomplished even if the government has no information on individual income or living standards. When the alternative to price controls is a poorly targeted explicit social safety net, the resource cost of queues might be more than compensated for by an improvement in the targeting of subsidies.price controls, tax evasion, queue-rationing, economic transition, income distribution
