If we multiply through by ifm+' and integrate from 0 to
r, there results

(1 ) frm-,y ≈ ʃ hm^'r sin u)e^i''m^'-',udu,
since the right-hand member vanishes to order m at least in
r. But (1') is of a form like (1) on the right except that m
is replaced by m — 1. Repeating the same type of procedure
wi — l times, we obtain finally

If now we replace the wι-fold integral on the left by a
simple integral, (4) becomes

But hm^mr') is even in r so that the integral on the
right in (4) is four times the same integral taken between 0
and τr∕2. Writing ʃ
=r sin и we thus obtain, as the equiva-
lent of (4), a linear integral equation of Abel type in

Conversely, if Am(∙r) as thus defined exists and is continuous,
the equation (1) will be satisfied by λm(j).

But the right-hand integral, after inverting the order of
integration, becomes
