Variations in the geometry of the basins of escape in a modified Hénon–Heiles potential

Demonstratio Mathematica
In this article, we show how the curves that limit the basins of escape in a version of a Hénon–Heiles potential with a singularity at the origin evolve with the energy.

Optimal control analysis of a mathematical model of malaria and COVID-19 co-infection dynamics

Journal of Biological Dynamics
In this paper, we analyze a deterministic model of malaria and Corona Virus Disease 2019 co-infection within a homogeneous population. We first studied the single infection model of each disease and then the co-infection dynamics.

A robust fitted numerical method for singularly perturbed turning point problems whose solution exhibits an interior layer

, 2020
In this paper we considerer singularly perturbed convection-diffusion-reaction problems with a turning point whose solution exhibits an interior layer. We establish bounds on the solution to these problems and their derivatives.

© Hindawi Publishing Corp. STAGNATION-POINT FLOW OF THE WALTERS ’ B ’ FLUID WITH SLIP

, 2004
The steady two-dimensional stagnation point flow of a non-Newtonian Walters ’ B ’ fluid with slip is studied. The fluid impinges on the wall either orthogonally or obliquely. A finite difference technique is employed to obtain solutions. 2000 Mathematics

The Numerical Computation of Homoclinic Orbits for Maps

, 1996
. Transversal homoclinic orbits of maps are known to generate shift dynamics on a set with Cantor like structure. In this paper a numerical method is developed for computation of the corresponding homoclinic orbits.

A scale-covariant pre-solve screening algorithm for scalar finite-difference discretizations on positive nonuniform meshes

Selecting a nonuniform finite-difference discretization before a reference solution is available requires a decision rule that uses assembled rows but does not confuse local consistency with stability.

Cyclic Reduction Method and Difference Wavelets

, 1994
. The study of a family of direct methods for solving sparse banded linear systems motivated by multiresolution decomposition gives a new look of the classical cyclic reduction method.

Multiresolutional Methods for Difference Equations

, 1994
. We develop a stable direct method with linear complexity for solving large banded sparse linear systems which are typical for the finite difference discretization of one-dimensional differential equations.

Superconvergence Estimates for the Numerical Computation of Heteroclinics for Maps

, 1998
In [5] a method for the approximation of heteroclinic orbits in parameterized time--discrete systems is given which applies both to transversal and quadratic tangential heteroclinics.
