Wavelets operational methods for fractional differential equations and systems of fractional differential equations
… method to solve some singular second order differential equations of Emden-Fowler type, a class of generalized Pantograph equations and Delay differential systems. A new operational matrix of fractional order derivative and integration based on this polynomial was also developed and used …

Stability theory of differential equations
… of determining the stability of a set of linear differential equations has been of interest to mathematicians and engineers for a considerable length of time. The problem is attacked by obtaining the characteristic equation of the original set of equations and determining the stability of this …

Analyzing How Students Learn Differential Equations
… we will analyze how to study how students learn differential equations. First, we will analyze what is generally taught in a differential equations course so we can establish the importance of what students are learning and give a sense of what they are learning. We will then establish what …

Uniqueness of Solutions of Differential Equations
Uniqueness of solutions for ordinary differential equations is studied. The classical theorems which guarantee uniqueness are surveyed, including discussion and examples. Other results concerning uniqueness are considered in the final chapter, including the relationship between convergence of …

Constructive Analysis of Partial Differential Equations
This thesis presents the results produced in the study of weak solutions of the Dirichlet Problem within Errett Bishop's constructive mathematics. It roughly falls into three major parts: a critical analysis of the classical approaches from a constructive point of view (Chapter 2); constructive …

Combat modelling with partial differential equations
… of this thesis we extend the Lanchester Ordinary Differential Equations and construct a new physically meaningful set of partial differential equations with the aim of more realistically representing soldier dynamics in order to enable a deeper understanding of the nature of conflict. Spatial …

Theoretical Analysis of Nonlinear Differential Equations
<p>Nonlinear differential equations arise as mathematical models of various phenomena. Here, various methods of solving and approximating linear and nonlinear differential equations are examined. Since analytical solutions to nonlinear differential equations are rare and difficult to determine, …

Algebraic structures in stochastic differential equations
… new numerical integration scheme for stochastic differential equations driven by Levy processes with uniformly lower mean square remainder than that of the scheme of the same strong order of convergence obtained by truncating the stochastic Taylor series. In doing so we generalize recent results …

Modeling complex systems with differential equations
Mathematical models have since long been successful in describing nature <br>and specifically dynamical processes of real-world systems. <br>Solely relying on mathematical <br>formalism, it has become possible to make adequate predictions of <br>the temporal evolution of systems of all kind and …

The Theory of Exponential Differential Equations
… thesis is a model-theoretic study of exponential differential equations in the context of differential algebra. I define the theory of a set of differential equations and give an axiomatization for the theory of the exponential differential equations of split semiabelian varieties. In particular, …

Schanuel Functions and Algebraic Differential Equations
… presented that the minimum order of an algebraic differential equation (ADE) satisfied by a given Schanuel function depends on the number of algebraically independent functions (over $\doubc (z))$ needed to build up the function. This extends a result of A. Babakhanian on towers of exponentials.

Stability Theorems for Stochastic Differential Equations
… stability property for a sequence of stochastic differential equations when the limit process is a generalized diffusion type equation. The main result is an extention of a theorem of K. Yamada.
