A new error evaluation for singularly perturbed problem with multi-point boundary condition

2020
Summary: We consider finite difference method to find best approximation of nonlinear singularly perturbed problem which contains multi-point boundary conditions. We surveyed the asymptotic estimates of the corresponding problem that needs to be solved with maximum principle. We constructed a finite difference scheme by using Bakhvalov mesh.

On a \(k\)-dimensional system of hybrid fractional differential equations with multi-point boundary conditions

2021
Summary: The fractional Sturm-Liouville fraction equations have considerable role applications in some different phenomena such as mechanical and electrical engineering, medicine and physics. Thus, it is better we review different versions of this equation. We study a \(k\)-dimensional system of Sturm-Liouville hybrid equations \(y\) using the \(\alpha\

Bi-singular type of a fractional-order multi-points boundary value condition problem

2021
Summary: Various fractional differential equations have been examined during the last decades. Among them, singular equations are more notable. In this article, by using control functions, the existence of a solution for a bi-singular fractional differential equation with multi-point initial value conditions is considered.

Essential boundary conditions and multi-point constraints in finite element analysis

Computer Methods in Applied Mechanics and Engineering, 2001
Elliptic problems with nonstandard boundary conditions are treated as variational problems with restrictions \[ \text{ minimize } \tfrac 12 x^T Sx-f^T x\quad \text{subject to } Cx=g. \] The saddle point equations \(Sx+C^T \lambda =f, ~Cx=g\) and their solvability are discussed from the algebraic viewpoint, i.e., \(g\in \text{Range}(C)\), \(\text{Ker ...
