Appendix
A: Pointsource diffusion in an infinite domain:
boundary and initial conditions
(PDF)
In this appendix we discuss how
the boundary and initial conditions for a points source in an
infinite, onedimensional domain are applied to find the solution
to the diffusion equation. The appendix presents a heuristic
argument followed by a rigorous application of the Fourier
Transform Method. For details of the solution, refer to Chapter
1.
