- Hello!
- Does anyone know what the Laplace transform of a product of functions is,
- please?
- A math professor told me that there is some "rare" theorem on this,
- but I hardly know where to look for it.
- He also said that it would be "some kind of convolution."
- Now of course the product of Laplace transforms of functions can be
- expressed by means of the convolution (1st convolution?) theorem. But
- what I am looking for is the Laplace transform of a product of (unknown)
- functions! There are well known formulas for the Laplace transforms of
- functions, of nth derivatives of functions, etc., in terms of values of
- the functions and their derivatives at various points, but . . . what
- about the Laplace transform of a product of functions?? Naturally, if
- that were known, it should apply to the special case of the Laplace
- transform of the second power of a function.
- I realize that the functions may have to satisfy various auxiliary conditions.
- Thanks!!! And, I hope I didn't ramble too much . . . .
- Carey
