 polynomial interpolation to fractional iteration andydude Long Time Fellow Posts: 509 Threads: 44 Joined: Aug 2007 12/23/2007, 05:27 AM Very nice discussion! I like the colors of the coefficients. I also briefly discuss this in this thread, and Jay discusses this in this thread, just to let you know, if you forgot. Also why do you call it U-tetration? I call it iterated decremented exponentials, since: iterated = repeating the same function over and over decremented = subtracting one from something exponential = a function from x to $b^x$ so an expression like $f(x) = b^x-1$ would be a decremented exponential, and an expression like $f^{\circ n}(x)$ would be an iterated decremented exponential.
