bilateral Laplace transform of a non-finite borel measure $\mu$, is it possible?
$$\int_{-\infty}^{+\infty} e^{-xt}\, \mathrm d\mu(t),\,\, x\in \mathbb{R}$$
If make sense to define a bilateral laplace transform of a non-finite measure, what changes in the region of convergence? That $x=0$ is not necessarly included in the region of convergence?
