A boundary jumps phenomenon in the integral boundary value problem for singularly perturbed differential equations

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
The article is devoted to the study of the asymptotic behavior of solving an integral boundary value problem for a third - order linear differential equation with a small parameter for two higher derivatives, provided that the roots of the "additional ...

Orthogonal Franklin system and orthogonal system of finite functions in numerical methods of boundary problems solving

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015
Possibilities of classical trigonometric Fourier series are substantially limited in 2-D and 3-D boundary value problems. Boundary conditions of such problems for areas with curvilinear boundaries often fails when using the classical Fourier series.

Boundary Correlators in Supergroup WZNW Models

open access: yes, 2008
We investigate correlation functions for maximally symmetric boundary conditions in the WZNW model on GL(1|1). Special attention is payed to volume filling branes.

$t$-Martin boundary of killed random walks in the quadrant [PDF]

open access: yes, 2016
We compute the $t$-Martin boundary of two-dimensional small steps random walks killed at the boundary of the quarter plane. We further provide explicit expressions for the (generating functions of the) discrete $t$-harmonic functions.

A mixed method for Dirichlet problems with radial basis functions

open access: yes, 2013
We present a simple discretization by radial basis functions for the Poisson equation with Dirichlet boundary condition. A Lagrangian multiplier using piecewise polynomials is used to accommodate the boundary condition.

Wave Functions of the Toda Chain with Boundary Interaction [PDF]

open access: yes, 2004
In this contribution, we give an integral representation of the wave functions of the quantum N-particle Toda chain with boundary interaction. In the case of the Toda chain with one-boundary interaction, we obtain the wave function by an integral ...

BOUNDARY VALUES OF ANALYTIC FUNCTIONS

open access: yesFar East Journal of Applied Mathematics, 2023
Let $D$ be a connected bounded domain in $\R^2$, $S$ be its boundary which is closed, connected and smooth. Let $Φ(z)=\frac 1 {2πi}\int_S\frac{f(s)ds}{s-z}$, $f\in L^1(S)$, $z=x+iy$. Boundary values of $Φ(z)$ on $S$ are studied. The function $Φ(t)$, $t\in S$, is defined in a new way. Necessary and sufficient conditions are given for $f\in L^1(S)$ to be

Workspace Definition in Parallelogram Manipulators: A Theoretical Framework Based on Boundary Functions

open access: yesTechnologies
Robots with parallelogram mechanisms are widely employed in industrial applications due to their mechanical rigidity and precise motion control. However, the analytical definition of feasible workspace regions free from self-collisions remains an open ...

Distance statistics in quadrangulations with a boundary, or with a self-avoiding loop

open access: yes, 2009
We consider quadrangulations with a boundary and derive explicit expressions for the generating functions of these maps with either a marked vertex at a prescribed distance from the boundary, or two boundary vertices at a prescribed mutual distance in ...
