# Category:Laplace Transforms

This category contains results about Laplace Transforms.
Definitions specific to this category can be found in Definitions/Laplace Transforms.

Let $f: \R_{\ge 0} \to \mathbb F$ be a function of a real variable $t$, where $\mathbb F \in \set {\R, \C}$.

The Laplace transform of $f$, denoted $\laptrans f$ or $F$, is defined as:

$\laptrans {\map f t} = \map F s = \displaystyle \int_0^{\to +\infty} e^{-s t} \map f t \rd t$

whenever this improper integral converges.

If this improper integral does not converge, then $\laptrans {\map f t}$ does not exist.
