On Integral Transforms [PDF]

open access: yesProceedings of the Edinburgh Mathematical Society, 1956
Titchmarsh and others [4] havo studied integral transform pairs of tho typeshowing how such pairs may be generated as a consequence of the relation which holds between the Mellin transforms of the kernels.
