Generalized arithmetic operator

but perhaps that is not what you are referring to.

If I had to write a recursion relation along the lines of what has been posted so far, I would say it is:


which is neither left- nor right-associative, if I understand the meaning of that phrase.
The ones that have been posted so far are
,
and
.

which are very similar, with the only difference being that the [x-1] operation on the right side is flipped.

But neither of these definitions result in the same [4] operator that I have.

etc.

well , i think i got it. tell me if i'm right

first lets notice that we have




so we have that if (note that since we have that )



and so



so the formulae that define all your hyperoperation family are

Quote:1)

2) (that is A1)

3) (that is A3)

with this three difinitions (and if we already have defined the function iteration) we can get all the values of your hyperoperations.

and if im right again we have too



I think i have already found this family somewhere, probably in the tetration FAQ pdf


-----

I've jsut noticed that we can maybe write it as functional equation

let

Quote:1')

2')

3')

the last can be rewritten in this way
3'')

and we have this property



and there is a name for this functional equation, I don't remember it but is a kind of abel functional equation i guess.

I'm sure that someone here can help you more about this.

EDIT:

BINGOOO found them. Cool

I knew it!
