Singularly perturbed boundary value problems
The author considers the system \(-\varepsilon^ 2 u''+g_ 1 (u,v,x,\varepsilon) =0\), \(v''+g_ 2(u,v,x,\varepsilon)=0\), \(v(0)=v(1)=u(0)=u(1)=0\), \(x \in[0,1]\), \(\varepsilon \neq 0\), where \(g_ 1\), \(g_ 2\) are continuous functions specially choosen by the author, \(\varepsilon\) is a small parameter.

In this paper, a numerical method based on Shishkin mesh for a singularly perturbed fourth order differential equation with a turning point exhibiting boundary layers is presented. In this method the problem is transformed into a weakly coupled system of

Singularly Perturbed Dirichlet Problems With Subquadratic Nonlinearities [PDF]
Boundary and interior layer theory is provided for a class of singularly perturbed Dirichlet problems with subquadratic nonlinearities in the derivative terms. The results obtained generalize and extend well-known results on the semilinear problem.

Extracellular Vesicle Lipids and Their Role in Delivery
ABSTRACT Small extracellular vesicles (sEVs) possess many advantageous characteristics which highlight their potential as nanocarriers for biomedical applications, including the ability to cross the blood brain barrier, improved biocompatibility and exhibit tissue tropism.

Boundary-layers for a Neumann problem at higher critical exponents
We consider the Neumann problem $$(P)\qquad - \Delta v + v= v^{q-1} \ \text{in }\ \mathcal{D}, \ v > 0 \ \text{in } \ \mathcal{D},\ \partial_\nu v = 0 \ \text{on } \partial\mathcal{D} ,$$ where $\mathcal{D} $ is an open bounded domain in $\mathbb{R}^N,$ $

Numerical Solution of Singularly Perturbed Delay Differential Equations with Layer Behavior
We present a numerical method to solve boundary value problems (BVPs) for singularly perturbed differential-difference equations with negative shift. In recent papers, the term negative shift has been used for delay.

A parameter uniform fitted mesh method for a weakly coupled system of two singularly perturbed convection-diffusion equations [PDF]
In this paper, a boundary value problem for a singularly perturbed linear system of two second order ordinary differential equations of convection- diffusion type is considered on the interval [0, 1]. The components of the solution of this system exhibit
