Half-iterate exp(z)-1: hypothese on growth of coefficients
#49
As for divergent summations I wanted to say something long ago but it was already said elsewhere :

" repeated borel summation "

@MISC {4246080,
    TITLE = {Has someone seen a discussion of the (divergent) summation of \(\sum\limits_{k=0}^\infty (-1)^k (k!)^2 \)?},
    AUTHOR = {Caleb Briggs (https://math.stackexchange.com/users/709...leb-briggs)},
    HOWPUBLISHED = {Mathematics Stack Exchange},
    NOTE = {URL:https://math.stackexchange.com/q/4246080 (version: 2021-09-30)},
    EPRINT = {https://math.stackexchange.com/q/4246080},
    URL = {https://math.stackexchange.com/q/4246080}
}


https://math.stackexchange.com/questions...limits-k-0

***

the validity of the borel summations matches the number of solutions for fractional iterates when taking in the correct direction.

nice.

***

sorry if im repeating said things , i have to catch up on reading ...


regards
