Hyperbolic Partial Differential Equations
We begin our study of finite difference methods for partial differential equations by considering the important class of partial differential equations called hyperbolic equations. In later chapters we consider other classes of partial differential equations, especially parabolic and elliptic equations. For each of these classes of equations we consider prototypical equations, with which we illustrate the important concepts and distinguishing features associated with each class. The reader is referred to other textbooks on partial differential equations for alternate approaches, e.g., Folland [18], Garabedian [22], and Weinberger [68]. After introducing each class of differential equations we consider finite difference methods for the numerical solution of equations in the class.
An Application of Generalized Laplace Transform in PDEs
Advances in Dynamical Systems and Applications
We would like to consider an application of generalized Laplace transform in partial differential equations(PDEs) by using the n-th partial derivatives. The tool of this research is the induction, and the proposed idea gives an easy solution to engineering problems by freely selecting the integer α in the definition.
Multi-dimensional Laplace transforms and systems of partial differential equations
International Mathematical Forum, 2006
The object of this paper is to establish new theorem and corollary involving systems of two-dimensional Laplace transforms containing several equations. This system can be used to calculate new Laplace transform pairs. In the second part, system of partial differential equations related to telegraph equation is solved by using the double Laplace transformation.
A note on integral transforms and partial differential equations
2010
In this study, we apply double integral transforms to solve partial differential equation namely double Laplace and Sumudu transforms, in particular the wave and poisson's equations were solved by double Sumudu transform and the same result can be obtained by double Laplace transform.
