Asymptotic convergence of the solution for singularly perturbed boundary value problem with boundary jumps

Қарағанды университетінің хабаршысы. Математика сериясы, 2018
The article is devoted to study of boundary value problem with boundary jumps for third order linear integro-differential equation with a small parameter at the highest derivatives, provided that additional characteristic equation’s roots have opposite ...

Asymptotics of Eigenvalues of First Boundary Value Problem for Singularly Pertubed Second-order Differential Equation with Turning Points

Моделирование и анализ информационных систем, 2015
We consider a linear differential equation of second order with a small factor at the highest derivative. We study the problem of the asymptotic behavior of the eigenvalues of the first boundary value problem (task Dirichlet) in situation when the turning ...

Minimal model for tidal bore revisited

New Journal of Physics, 2019
This develops a recent analysis of gentle undular tidal bores (2018 New J. Phys. 20 053066) and corrects an error. The simplest linear-wave superposition, of monochromatic waves propagating according to the shallow-water dispersion relation, leads to a ...

Relaxation Oscillations in a System with Delays Modeling the Predator-Prey Problem

Моделирование и анализ информационных систем, 2013
A new asymptotic method for investigating complex relaxation oscillations of a system with delay was offered. Applying it, we can reduce the problem of predator-prey system dynamics to problem of one-dimensional maps analysis.

On the Diophantine Equation z(n) = (2 − 1/k)n Involving the Order of Appearance in the Fibonacci Sequence

Mathematics, 2020
Let ( F n ) n ≥ 0 be the sequence of the Fibonacci numbers. The order (or rank) of appearance z ( n ) of a positive integer n is defined as the smallest positive integer m such that n divides F m .

Full Waveform Inversion Based on an Asymptotic Solution of Helmholtz Equation

Geosciences, 2023
This study considers the full waveform inversion (FWI) method based on the asymptotic solution of the Helmholtz equation. We provide frequency-dependent ray tracing to obtain the wave field used to compute the FWI gradient and calculate the modeled data.

The error term of the sum of digital sum functions, in arbitrary bases [PDF]

Notes on Number Theory and Discrete Mathematics
Let k be a non-negative integer and p>1 be a positive integer. Let sₚ(k) be the sum of digits of k written in base p. In 1940, Bush proved that Aₚ(x)=Σₖ≤ₓsₚ(k) is asymptotic to ((p-1)/2)xlogₚx.
