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 ...

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.

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.
