Photon sphere for a dyonic black hole corresponding to Toda chain

Vladimir D. Ivashchuk, Evgeny E. Trubach

We consider a dilatonic dyon black hole solution with a gravitational radius of and two charges, (electric) and (magnetic), within the framework of a four-dimensi…

Reproducible Research in Network Modeling

Anna M. Ermolayeva, Tatyana R. Velieva, Anna A. Zhivtsova +2

Background: When we model networks, there is a problem of obtaining experimental data to verify other model approaches. And even if there are some experimental data, it is necessar…

Third-order inverse spectral problem with the three-point boundary conditions

Natalia P. Bondarenko

In this paper, we study a new inverse spectral problem that consists in the recovery of the third-order differential equation from two spectra corresponding to the boundary conditi…

-algebras of transmission problems and elliptic boundary value problems with shift operators

Alexandre Baldare, Vladimir E. Nazaikinskii, Anton Yu. Savin +1

We study the Fredholm solvability for a new class of nonlocal boundary value problems associated with group actions on smooth manifolds. Namely, we consider the case in which the g…

Persistence and Transition Varieties in Scalar Field Cosmology

Spiros Cotsakis

We develop a unified bifurcation-theoretic description of Friedmann--Robertson--Walker cosmologies with a scalar field, a barotropic fluid of index , and spatial curvature. For…

Photon Sphere for a Dilatonic Dyonic Black Hole in a Model with an Abelian Gauge Field and a Scalar Field

V. D. Ivashchuk, U. S. Kayumov, A. N. Malybayev +1

Dilatonic dyon black hole solution with gravitational radius and two charges and (electric and magnetic ones) in the gravitational model with one scalar fiel…
