about kouznetsov's tetration.
lim b -> oo f(a + bi) = fixpoint exp.
that seems true for integer a and integer b but is that true for all real a and b ?
it was said to be periodic , so i guess not.
but is it bounded ? it seems like a double periodic limit at oo then.
in general double periodic is unbounded in its period ...
but this is a special case ; approaching at oo.
the cauchy contour would work better if we truely had :
lim b -> oo f(a + bi) = fixpoint exp.
that would require that f(x + i) = g(f(x)) and g(x) has fix exp as a strong and unique fixpoint ( i think ).
in that case the cauchy contour should work better ! not ?
but how to construct such a solution ?
this related to another recent post i made : " twice a superfunction ".
