 Should tetration be a multivalued function? andydude Long Time Fellow Posts: 509 Threads: 44 Joined: Aug 2007 01/13/2016, 08:24 AM @marraco, @tommy That certainly is a cool equation, even if it is easily provable. @everyone Also, I think I can express my earlier comment in different words now. Tetration is defined as the 1-initialized superfunction of exponentials. The previous functions discussed earilier are 3-initialized and 5-initialized, which makes them, not tetration, by definition. However, if there is an analytic continuation of the 1-initialized superfunction that overlaps with the 3-initialized superfunction, AND if on the overlap f(0) = 3, then they can be considered branches of the same function. But until that is proven, I don't think it's accurate to say that they're all "tetration". They are, however, iterated exponentials in the sense that they extend $\exp_b^n(3)$ to non-integer n. And so I would probably write these functions as $\exp_b^n(1),\, \exp_b^n(3),\, \exp_b^n(5)$ instead of saying that ${}^{n}b$ is a multivalued function that returns all three. « Next Oldest | Next Newest »
