A PDE is an equation which contains partial derivatives, such as$$ \\frac{\\partial u}{\\partial t}=\\frac{\\partial^2 u}{\\partial {x}^2} $$in which u is regarded as function of length x and time t. There is no real unified theory for PDEs. They exhibit their own ...

H s (R n ) (the s Sobolev space) is a Banach space that contains all functions that along with their distributional s−derivatives belong to L 2 (R n ). This norm AN INTRODUCTION TO DISPERSIVE PARTIAL DIFFERENTIAL EQUATIONS. 3 is equivalent (through the basic properties of the Fourier ...
• This is an equation with derivatives of at least two variables in it. • In general, partial differential equations are much more difficult to solve analytically than are ordinary differential equations What Does a PDE Look Like • Let u be a function of x and y. There are ...
Many of the designations used by manufacturers and sellers to distinguish their products are claimed as trademarks. Where those designations appear in this book, and Addison-Wesley was aware of a trademark claim, the designations have been printed with initial capital letters or in...

The gradient of a function at a point is the vector of its partial derivatives: \boldsymbol{g}=\frac{\partial f}{\partial \boldsymbol{x}}=\nabla f=\left(\begin{array}{c} \frac{\partial f}{\partial x_1} \\ \vdots \\ \frac{\partial f}{\partial x_n} \end{array}\right) ...
