Asymptotic analysis of the axisymmetric problem for the transverse compression of a thin elastic disk in the case of mixed boundary conditions along its faces [PDF]

Известия Саратовского университета. Новая серия: Математика. Механика. Информатика
The axisymmetric problem for the transverse compression of a thin elastic disk is considered in slip absence.  An asymptotic solution for the interior stress-strain state is constructed.

Computation in an Asymptotic Expansion Method [PDF]

SSRN Electronic Journal, 2009
An asymptotic expansion scheme in finance initiated by Kunitomo and Takahashi [15] and Yoshida [68] is a widely applicable methodology for analytic approximation of the expectation of a certain functional of diffusion processes. [46], [47] and [53] provide explicit formulas of conditional expectations necessary for the asymptotic expansion up to the ...

Low Mach dynamics of interface and flow fields in thermally conducting fluids

Frontiers in Applied Mathematics and Statistics
Unstable interfaces govern many processes in fluids, plasmas, materials, in nature and technology. In distinct physical environments, the interface dynamics exhibit similar characteristics and couple micro to macro scales.

The asymptotic analysis of free vibrations of a cylindrical shell joined with annular plates [PDF]

Известия Саратовского университета. Новая серия: Математика. Механика. Информатика
Low frequencies and vibration modes of a closed circular cylindrical shell joined with annular plates are obtained by means of asymptotic methods. Two types of vibrations, corresponding to narrow and wide plates, are analyzed. If the width of the ring is

Asymptotic Methods

, 2021
In this lecture notes, we will introduce Asymptotics, then we will give a short glimpse on Perturbation theory (regular versus singular), which plays a crucial role especially in theoretical physics. Our goal is to find Asymptotic series that approximates the values of integrals depending on some parameter or the solutions of differential equations ...

Construction and analysis of nonlinear oscillation modes of a three-link pendulum by asymptotic methods [PDF]

Известия Саратовского университета. Новая серия: Математика. Механика. Информатика
This article is devoted to the study of nonlinear oscillations of one of the most common systems with three degrees of freedom – a three-link mathematical pendulum, the parameters of all weightless links and all end loads of which are assumed to be
