On the initial-value problem of the Maxwell-Lorentz equations. [PDF]

open access: yes, 2010
We consider the Maxwell-Lorentz equations, i.e., the equation of motion of a charged dust coupled to Maxwell's equations, on an arbitrary general-relativistic spacetime.

Bethe equations `on the wrong side of the equator' [PDF]

open access: yesJournal of Physics A: Mathematical and General, 1999
We analyse the famous Baxter's $T-Q$ equations for $XXX$ ($XXZ$) spin chain and show that apart from its usual polynomial (trigonometric) solution, which provides the solution of Bethe-Ansatz equations, there exists also the second solution which should corresponds to Bethe-Ansatz beyond $N/2$.

ON A FUNCTIONAL EQUATION [PDF]

open access: yesThe Quarterly Journal of Mathematics, 1958
We have recently discussed in (1) the general solution of a certain functional equation arising in statistical thermodynamics, and we propose in this note to deal with another functional equation arising from the same source(2).The problem is to obtain the most general function f(x) which, for all positive integral values of m, n, satifies the ...

The SQG Equation as a Geodesic Equation [PDF]

open access: yesArchive for Rational Mechanics and Analysis, 2016
We demonstrate that the surface quasi-geostrophic (SQG) equation given by $$θ_t + \left= 0,\;\;\; θ= \nabla \times (-Δ)^{-1/2} u,$$ is the geodesic equation on the group of volume-preserving diffeomorphisms of a Riemannian manifold $M$ in the right-invariant $\dot{H}^{-1/2}$ metric.

Computational framework for the regularized 20-moment equations for non-equilibrium gas flows [PDF]

open access: yes, 2008
This paper presents a framework for solving the regularized 20-moment equations consisting of a set of transport-like governing equations, the required constitutive closure, re-casting of the equations in second-order partial derivative form and ...

Introduction of an Auxiliary Breaker into the Generator-Transformer Block for Energy Saving in Open Switchgear Circuits of Power Plants

open access: yesИзвестия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2023
A need in finding of new ways of energy saving at open switchgears of power plants is substantiated. In order to increase energy saving efficiency, an auxiliary breaker is suggested to be inserted between a transformer of a block and its two high-voltage
