Black holes of multiple horizons without mass inflation
Changjun Gao, Toktarbay Saken
Mass inflation is a phenomenon happened in the vicinity of inner horizon in two-horizon spacetime. It is shown that the mass of initially small perturbations will grow exponentiall…
Non-singular bouncing cosmology in gravity with energy condition violations
A. Zhadyranova, M. Koussour, V. Zhumabekova +3
The singularity and inflationary problems have posed significant challenges for understanding the universe's origin and evolution. Bouncing cosmology has emerged as a promising alt…
Gravitational field of slightly deformed naked singularities
Saken Toktarbay, Hernando Quevedo, Medeu Abishev +1
We derive a particular approximate solution of Einstein equations, describing the gravitational field of a mass distribution that slightly deviates from spherical symmetry. The dev…
New complex EAS installation of the Tien Shan Mountain Cosmic Ray Station
A. P. Chubenko, A. L. Shepetov, V. P. Antonova +22
We present a description of the new complex installation for the study of extensive air showers which was created at the Tien Shan mountain cosmic ray station, as well as the resul…
Conditional expectation on non-commutative and spaces : semifinite case
D. Dauitbek, K. S. Tulenov
In this paper we investigate the conditional expectation on the non-commutative and spaces associated with se…
Extreme points of the set of elements majorised by an integrable function: Resolution of a problem by Luxemburg and of its noncommutative counterpart
D. Dauitbek, J. Huang, F. Sukochev
Let be an arbitrary integrable function on a finite measure space . We characterise the extreme points of the set of all measurable functions on maj…
Double-Layer Potentials for a Generalized Bi-Axially Symmetric Helmholtz Equation II
Abdumauvlen Berdyshev, Anvar Hasanov, Tuhtasin Ergashev
The double-layer potential plays an important role in solving boundary value problems for elliptic equations. All the fundamental solutions of the generalized bi-axially symmetric…
A New Mathematical Formulation of the Governing Equations for the Chemical Compositional Simulation
Bakhbergen E. Bekbauov, Aidarkhan Kaltayev, Abdumauvlen Berdyshev
It is the purpose of this work to develop new approach for chemical compositional reservoir simulation, which may be regarded as a sequential method. The development process can be…
Unique solvability of a non-local problem for mixed type equation with fractional derivative
E. T. Karimov, A. S. Berdyshev, N. A. Rakhmatullaeva
In this work we investigate a boundary problem with non-local conditions for mixed parabolic-hyperbolic type equation with three lines of type-changing with Caputo fractional deriv…
On the existence of eigenvalues of a boundary value problem with transmitting condition of the integral form for parabolic-hyperbolic equation
Abdumauvlen S. Berdyshev
In the paper, we investigate a local boundary value problem with transmitting condition of the integral form for mixed parabolic-hyperbolic equation with non-characteristic line of…
On Convergence in the Spatial AK Growth Models
Gani Aldashev, Serik Aldashev, Timoteo Carletti
Recent research in economic theory attempts to study optimal economic growth and spatial location of economic activity in a unified framework. So far, the key result of this litera…
