f(s),h(s) and "hairs".

[Gottfried]

Now let hair(a),hair(b) be the continu iterations paths(curves) of iterated exponentials of a,b.

So the hair/path/curves starts at a,b and then follow the direction exp^[r](a) or exp^[r](b) for real r >=0.

Hello Tommy, is  your definition of a hair compatible with that of Devaney? I ask, because I was unable so far to completely understand what Devaney meant: a (discrete) orbit or a (continuous) trajectory... (I couldn't make it sure even by the secondary literature that I had/found so far and especially I lack the original/introductional Devaney's book)
