I am reading about the The convolution operation, and the notion Laplace transformable functions is mentioned there.
Doe anyone know what is the definition of Laplace transformable functions?
Thank you!

What is doubtless meant by $f(x)$ being Laplace transformable is that $\int_0^\infty e^{-sx} f(x) \, dx$ converges, at least for certain values of $s \in \mathbb{R}$ or $\mathbb{C}$.
