ABSTRAM For final integral transformations Sneddon ffefs .2, 17 introduced
kernels, which'include Bessel functions, in orde'r to study.the
physical state of.bodies possessing cylindrical symmetry. The
transformations of this kind he denoted as Hankel final integral
transformations. A general method for solving certain boundary-.

the authors introduce the analogous difference formulas (1!) and (12),
and derive the implicit difference formulas (13) - (14) analogrous to
(6) -- (7). These implicit difference formulan are aomewhat more complex
than the explicit ones, but they permit an increase of the step. Pinally,
