Neutrino beaming in ultraluminous X-ray pulsars as a result of gravitational lensing by neutron stars

Alexander A. Mushtukov, Alexander Y. Potekhin, Ivan D. Markozov +6

X-ray pulsars experiencing extreme mass accretion rates can produce neutrino emission in the MeV energy band. Neutrinos in these systems are emitted in close proximity to the stell…

Symplectic geometry of electrical networks

Boris Bychkov, Vassily Gorbounov, Lazar Guterman +1

In this paper we relate a well-known in symplectic geometry compactification of the space of symmetric bilinear forms considered as a chart of the Lagrangian Grassmannian to the sp…

Optimal Lagrange Interpolation Projectors and Legendre Polynomials

Mikhail Nevskii

Let $K$ be a convex body in $R^{n}$ , and let $Π_{1} (R^{n})$ be the space of polynomials in $n$ variables of degree at most $1$ . Given an $(n + 1)$ -element set $Y\subset…

Matrix Lax pairs under the gauge equivalence relation induced by the gauge group action and Miura-type transformations for lattice equations

Sergei Igonin

In this paper we explore interconnections of differential-difference matrix Lax representations (Lax pairs), gauge transformations, and discrete Miura-type transformations (MTs), w…

On 1-skeleton of the cut polytopes

Andrei V. Nikolaev

Given an undirected graph $G = (V, E)$ , the cut polytope $CUT (G)$ is defined as the convex hull of the incidence vectors of all cuts in $G$ . The 1-skeleton of $\mathrm{CUT}…
