Singular perturbation boundary and interior layers problems with multiple turning points

Boundary Value Problems
In the study of singularly perturbed boundary problems with turning points, the solution undergoes sharp changes near these points and exhibits various interior phenomena.

Singularly Perturbed Higher Order Boundary Value Problems

Journal of Differential Equations, 1994
The author considers the boundary value problem \(\varepsilon^ 2\cdot y^{(n)}= f(x,y,\dots, y^{(n-3)},y^{(n-2)})\), \(n\geq 3\), \({\mathcal B}y= 0\), \({\mathcal L}y= 0\), \(x\in \langle 0,1\rangle\), where \(\varepsilon> 0\), \(y^{(i)}= (d^ i/dt^ i)y\), \(f= f(x,z,v)\), \(f: \langle 0,1\rangle\times \mathbb{R}^{n-2}\times \mathbb{R}\to \mathbb{R}\), \

Analytical Solutions and Computer Modeling of a Boundary Value Problem for a Nonstationary System of Nernst–Planck–Poisson Equations in a Diffusion Layer

Mathematics
This article proposes various new approximate analytical solutions of the boundary value problem for the non-stationary system of Nernst–Planck–Poisson (NPP) equations in the diffusion layer of an ideally selective ion-exchange membrane at overlimiting ...
