Parameter Class for Solving Delay Differential Equations
Journal Title: JOURNAL OF ADVANCES IN MATHEMATICS - Year 2015, Vol 10, Issue 9
Abstract
In this paper a parameter class of Linear multistep method are applied to solve delay differential equations of the form y’(t) = f(t; y(t); y(t- t(t))), (t >0) subject to the initial condition y(t) = j (t) for tmin =<t <= 0 , t > 0 . The stability properties when the methods were applied to the test equation with a fixed delay t ; y’(t) = λy(t) + µy(t - t ); t ³ 0; are studied λ; µ are complex constants and Ф(t) is a continuous complex-valued function. The stability regions are plotted and numerical results are introduced.

The Continuous Dependence and Numerical Approximation of the Solution of the Quasilinear Pseudo-Parabolic Problem with Periodic Boundary Condition
In this paper we consider a pseudo- parabolic equation with a periodic boundary condition and we prove the stability of a solution on the data. We give a numerical example for the stability of the solution on the data.
Solutions and comparison theorems for anticipated backward stochastic differential equations with non-Lipschitz generators
This paper is devoted to solving multidimensional anticipated backward stochastic differential equations (anticipated BSDEs for short) with a kind of non-Lipschitz generators. We establish the existence and uniqueness re...
A Symmetry Hidden at The Center of Quantum Mathematics Causes a Disconnect Between Quantum Math and Quantum Mechanics
Although quantum mathematics is the most successful science ever, that does not mean we live in the universe described by quantum mechanics. This article is entirely based on symmetry. Two symmetrical universes could hav...
{The New Generalized of exp(-a(b)) Expansion Method And its Application To Some Complex Nonlinear Partial Differential Equations
In this article, the generalized expansion method has been successfully implemented to seek traveling wave solutions of the Eckaus equation and the nonlinear Schr\"{o}dinger equation. The result reveals that the me...
A Stochastic Process Degradation Model for effects of 3-year GH replacement therapy for GH deficiency on bone mineral density in younger and elderly adults
The paper presents a stochastic gamma process model to account for both population (i.e sampling) and temporal variability associated with a degradation process that typically increases the probability of failure with th...
