 tetration base conversion, and sexp/slog limit equations sheldonison Long Time Fellow Posts: 641 Threads: 22 Joined: Oct 2008 02/20/2009, 02:51 PM (This post was last modified: 02/20/2009, 05:15 PM by sheldonison.) bo198214 Wrote:But this question is different from whether $\text{slog}_a(x)-\text{slog}_b(x)$ converges to a constant, if we assume $a,b>e^{1/e}$. If $\text{slog}_a(x)-\text{slog}_b(x)$ does converge for $x\to\infty$ then - as $\text{sexp}_b$ goes to infinity - also $\text{slog}_a(\text{sexp}_b(x))-x$ converges. But this means that $\text{slog}_a(\text{sexp}_b(x))$ can not converge to a constant and vice versa. typo: $\text{slog}_a(\text{sexp}_b(x))-x$ is what converges to a cyclic 1-cycle function as x grows larger and may converge to a constant as x grows larger for some definitions of slog/sexp. Quote:But it never gets completely linear, doesnt it? Otherwise it would not be analytic. no, of course not. But I think the contributions of the higher order terms versus a linear estimate between the second and third terms, or between $\text{log}_b(e)$ and $\text{log}_b(\text{log}_b(e))$, becomes insignificant. I plan to try and show that the second and higher order derivatives for the two points, contribute an insignificant delta as b approaches $e^{1/e}$, and that in the limit, the linear term dominates the higher order terms by an arbitrarily large amount, and that the linear approximation suffices as a definition for the tetration for base b. I had originally intended this thread to be a search for other links about about base changes for tetration. I seem to have gotten side tracked on to defining the sexp function for real numbers for bases $>e^{1/e}$. - Sheldon Levenstein « Next Oldest | Next Newest »
