A NSFD method for the singularly perturbed Burgers-Huxley equation
This article focuses on a numerical solution of the singularly perturbed Burgers-Huxley equation. The simultaneous presence of a singular perturbation parameter and the nonlinearity raise the challenge of finding a reliable and efficient numerical ...

The braiding for representations of q-deformed affine $sl_2$ [PDF]
We compute the braiding for the `principal gradation' of $U_q(\hat{{\it sl}_2})$ for $|q|=1$ from first principles, starting from the idea of a rigid braided tensor category.

Exponentially fitted tension spline method for singularly perturbed differential difference equations [PDF]
In this article, singularly perturbed differential difference equations having delay and advance in the reaction terms are considered. The highest-order derivative term of the equation is multiplied by a perturbation parameter ε taking arbitrary values ...

A rigorous setting for the reinitialization of first order level set equations [PDF]
In this paper we set up a rigorous justification for the reinitialization algorithm. Using the theory of viscosity solutions, we propose a well-posed Hamilton-Jacobi equation with a parameter, which is derived from homogenization for a Hamiltonian ...

Robust numerical method for singularly perturbed differential equations with large delay
In this paper, a singularly perturbed differential equation with a large delay is considered. The considered problem contains a large delay parameter on the reaction term. The solution of the problem exhibits the interior layer due to the delay parameter

In this paper an initial value problem for aВ non-linear system of two singularly perturbed first orderВ differential equations is considered on the interval (0,1].The components of the solution of this system exhibit initialВ layers at 0. A numerical method composed of a classicalВ finite difference scheme on a piecewise uniform ShishkinВ mesh is ...
