- 1.These results apply either to functions having the necessary behavior at infinity to allow integration by parts, or to generalized functions with no restrictions.Google Scholar
- 2.The theory of generalized functions may be extended quite simply to several variables, but we do not need to concern ourselves with the details here.Google Scholar
- 3.See Section 9.5.Google Scholar
- 5.This is an example of the collisionless linear transport equation. See Section 19.6 for an example of the use of this Green’s function in the solution of the linear transport equation with collisions.Google Scholar
- 6.See Ditkin & Prudnikov (1970) for more information on double Laplace transforms.Google Scholar
- 7.We use the notation ℒ[f (x,y); y → p] so as to indicate which variable is transformed. Thus ℒ[f (x,y); y → p] is a function of x and p.Google Scholar
