WebThe generating function for the Bessel functions is. Φ(x, h): = e1 2x ( h − 1 / h), and the Bessel functions are defined implicitly by. Φ(x, h) = ∞ ∑ n = − ∞Jn(x)hn. This equation is analogous to Eq. (3.4) for the Legendre polynomials, but notice that the sum over n includes both positive and negative values.

Applying the Bromwich integral to a cumulant generating function

An integral formula for the inverse Laplace transform, called the Mellin's inverse formula, the Bromwich integral, or the Fourier–Mellin integral, is given by the line integral: $${\displaystyle f(t)={\mathcal {L}}^{-1}\{F(s)\}(t)={\frac {1}{2\pi i}}\lim _{T\to \infty }\int _{\gamma -iT}^{\gamma +iT}e^{st}F(s)\,ds}$$ where … See more In mathematics, the inverse Laplace transform of a function F(s) is the piecewise-continuous and exponentially-restricted real function f(t) which has the property: See more • InverseLaplaceTransform performs symbolic inverse transforms in Mathematica • Numerical Inversion of Laplace Transform with Multiple Precision Using the Complex Domain See more • Tables of Integral Transforms at EqWorld: The World of Mathematical Equations.
