As 6, must satisfy (10) for all values of «,, this is also the case 
with each of the products XZ, of which 6, is built up, hence 
also with A,. When in (10) the value of AR, given by (12) is sub- 
stituted for 6,, we find:

This equation has an infinite number of roots, which ranged ac-

To every root § belongs a value of the function A,. These fune-

Like (11a), (116) has also two particular solutions, one of which 
becomes zero for 7, = ©, and the other infinite. In conneetion with 
(9) the former must be chosen. Apart from a constant factor, this
