Meijer transform

The integral transform

where is the Whittaker function (cf. Whittaker functions). The corresponding inversion formula is

For the Meijer transform becomes the Laplace transform; for it becomes the -transform

where is the Macdonald function.

The Varma transform

reduces to a Meijer transform.

The Meijer -transform (or the Meijer–Bessel transform) is the integral transform

If the function is locally integrable on , has bounded variation in a neighbourhood of the point , and if the integral

converges, then the following inversion formula is valid:

For the Meijer -transform turns into the Laplace transform.

The Meijer transform and Meijer -transform were introduced by C.S. Meijer in [1] and, respectively, .
