Hmm ... you mean Woon's formula ...
You can also call it Newton's formula:
Woon just applied this to linear operators
However we cant calculate with iterations as with powers, because the composition is no more right distributive.
The interesting thing however is that both expansions together are then again valid:
And I think this is new. Especially that the iteration by this formula is the same as regular iteration (which is sure for elliptic iteration, other cases are still to prove).
