# Inverse laplace transform pf infinite product

In summary, an inverse Laplace transform of an infinite product is a mathematical operation that converts a function from the Laplace domain to the time domain, resulting in an infinite product of time domain functions. It is calculated using the residue theorem and is useful for solving differential equations and other mathematical problems. Some applications include signal processing, control systems, and probability theory. However, it can only be applied to analytic functions with a finite number of poles and no singularities on the real axis, and the convergence of the infinite product must also be considered.

I have to do inverse laplace transform of infinite product that is shown below. Can somebody help me with that?

$$\displaystyle g(t) =\dfrac{ e^{-nt}}{(n-1)!} (e^t-1)^{n-1}$$

I suspect it can be proven using induction. Have a go.

## 1. What is the inverse Laplace transform of an infinite product?

The inverse Laplace transform of an infinite product is a mathematical operation that takes the Laplace transform of an infinite product function and returns the original function in the time domain. It is denoted by the symbol <img src="https://latex.codecogs.com/gif.latex?{\mathcal{L}^{-1}\left\{\prod_{k=1}^{\infty}F_k(s)\right\}}" title="{\mathcal{L}^{-1}\left\{\prod_{k=1}^{\infty}F_k(s)\right\}}" />

## 2. How is the inverse Laplace transform of an infinite product calculated?

The inverse Laplace transform of an infinite product can be calculated using the inverse Laplace transform formula, which is given by <img src="https://latex.codecogs.com/gif.latex?{\mathcal{L}^{-1}\left\{\prod_{k=1}^{\infty}F_k(s)\right\}=\int_{c-i\infty}^{c+i\infty}\prod_{k=1}^{\infty}F_k(s)e^{st}\mathrm{d}s}" title="{\mathcal{L}^{-1}\left\{\prod_{k=1}^{\infty}F_k(s)\right\}=\int_{c-i\infty}^{c+i\infty}\prod_{k=1}^{\infty}F_k(s)e^{st}\mathrm{d}s}" />
