The two essentially different concepts of “form” and “function” are sometimes confused in elementary text-books, and in this note I set out to stress one or two important formal results, in particular the formal interpretation of the binomial theorem for a negative integral exponent. It has been one specific problem, namely the establishing of the Wronski relations
a 1-h 1=0, a 2-a 1 h 1+h 2=0, .. ,a k -a k-1 h 1+...+(-1)k h k =0,...
connecting the elementary symmetric functions ar and the homogeneous prodcut sums hr , which has recently focused my attention on this subject and prompted me to write down a few observations.
