The Gauss function in the integral (a1) is the hypergeometric series for and for one can understand it as an analytic continuation, which can be obtained from the Mellin–Barnes integral representation [a3].
The following integral transform is also called the Olevskii transform. It is an integral over the index of the Gauss function,
Here, is an arbitrary odd function belonging to the space , where
The transform (a2) maps this space onto the space and the Parseval equality holds:
