On the response function of a degenerate Bose gas

Low temperature physics (Woodbury, N.Y., Print), 2019
The space-time density-density response function for degenerate ideal Bose gas is considered. On this basis, it is shown that upon exposure to a weak external field, a space-time wave of average non-uniform density fluctuation is formed in the ideal Bose

Overtaking Interactions of Multi-Ion Acoustic Shock Waves in a Magnetized Degenerate Plasma: An Application in White Dwarfs

Journal of Nanoelectronics and Optoelectronics, 2022
Overtaking interactions are examined of multi-ion acoustic shock waves in magnetized degenerate quantum plasmas comprising inertial non-relativistic heavy and light ions having positive charges ultra-relativistic degenerate inertialess electrons.

Boundedness of Classical Solutions to a Degenerate Keller–Segel Type Model with Signal-Dependent Motilities

Acta Applicandae Mathematicae - An International Survey Journal on Applying Mathematics and Mathematical Applications, 2020
In this paper, we consider the initial Neumann boundary value problem for a degenerate kinetic model of Keller–Segel type. The system features a signal-dependent decreasing motility function that vanishes asymptotically, i.e., degeneracies may take place

Exponential and gamma form for tail expansions of first-passage distributions in semi-markov processes

Advances in Applied Probability, 2022
We consider residue expansions for survival and density/mass functions of first-passage distributions in finite-state semi-Markov processes (SMPs) in continuous and integer time.

On coupled nonlocal Schrödinger–Kirchhoff system with singular exponential nonlinearity in R N

Electronic Journal of Qualitative Theory of Differential Equations
This paper is concerned with the existence of solutions for parameters dependent Schrödinger–Kirchhoff system driven by nonlocal integro-differential operators with singular Trudinger–Moser nonlinearity in the whole Euclidean space R N . These

Degenerate Schrödinger--Kirchhoff {(p,N)}-Laplacian problem with singular Trudinger--Moser nonlinearity in ℝ N

Forum mathematicum
In this paper, we deal with the existence of nontrivial nonnegative solutions for a ( p , N ) {(p,N)} -Laplacian Schrödinger–Kirchhoff problem in ℝ N {\mathbb{R}^{N}} with singular exponential nonlinearity. The main features of the paper are the ( p , N )

Color Image Encryption Algorithm Based on Non-degenerate Chaotic System and Dynamic DNA Encoding

2024 3rd International Joint Conference on Information and Communication Engineering (JCICE)
With the exponential surge in user-uploaded and shared image data, the vulnerability to privacy breaches has become increasingly pronounced. Designing encryption algorithms utilizing chaotic systems and applying them to digital image encryption serves as

Spiral Exponential Function — Chapter 4: Degeneration

This chapter explores the concept of degeneration within the framework of spiral exponential functions. Specifically, it examines how higher-order derivatives of motion (such as jerk and snap) vanish under certain angular conditions defined by . This leads to a natural transition from complex spiral dynamics to lower-order, classical motion forms like ...
