Are there general boundary conditions for the wave equation PDE at infinity? If there is, could someone suggest a book/monograph that deals with these boundary conditions?
More specifically, if we have the following wave equation:
[tex]
\[
\nabla ^2 p = A\frac{{\partial ^2 p}}{{\partial t^2 }} + B\frac{{\partial p}}{{\partial t}}
\]
[/tex]
how would I select boundary conditions at infinity to ensure that the wave will continue to propagate approaching infinity?
