Global and Blow-Up Solutions for a Nonlinear Diffusion System with a Source and Nonlinear Boundary Conditions

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2023
In this paper, we study the global solvability and unsolvability of a nonlinear diffusion system with nonlinear boundary conditions in the case of slow diffusion.

Gaps of size 2, 4, and (conditionally) 6 between successive odd composite numbers occur infinitely often [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
The infinite sequence of gaps (first differences) between successive odd composite numbers contains only the numbers 2, 4, and 6. We prove that, for any natural number k, the sequence of gaps contains infinitely many k-tuplets of consecutive gaps all ...

Asymptotic independence for unimodal densities [PDF]

open access: yes, 2009
Asymptotic independence of the components of random vectors is a concept used in many applications. The standard criteria for checking asymptotic independence are given in terms of distribution functions (dfs).

Asymptotic Expansions of Eigenvalues of Periodic and Antiperiodic Boundary Problems for Singularly Perturbed Second Order Differential Equation with Turning Points

open access: yesМоделирование и анализ информационных систем, 2016
For a second order equation with a small factor at the highest derivative the asymptotic behavior of all eigenvalues of periodic and antiperiodic problems is studied. The main assumption is that the coefficient at the first derivative in the equation is the

Asymptotics of Solutions of the Generalized Hutchinson’s Equation

open access: yesМоделирование и анализ информационных систем, 2015
We discuss the dynamics of the Hutchinson’s equation and its generalizations. An estimate of the global stability region of a positive steady state is obtained. The main results refer to existence, stability and asymptotics of a slow oscillating solution.

Asymptotic Formulation for the Rayleigh Wave on a Nonlocally Elastic Half-Space

open access: yesVibration, 2023
This paper deals with the Rayleigh wave, propagating on a nonlocally elastic, linearly isotropic half-space, excited by a prescribed surface loading. The consideration develops the methodology of hyperbolic–elliptic models for Rayleigh and Rayleigh-type ...

A Systematically Reduced Mathematical Model for Organoid Expansion

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
Organoids are three-dimensional multicellular tissue constructs. When cultured in vitro, they recapitulate the structure, heterogeneity, and function of their in vivo counterparts. As awareness of the multiple uses of organoids has grown, e.g.
