Positive Values of a Holomorphic Function connected with the Collatz Problem

open access: yesPositive Values of a Holomorphic Function connected with the Collatz Problem
We show that an entire holomorphic function F(z) connected with the Collatz problem (cf. [8]) takes positive value F(x) for all positive real variable x.

Negative Values of a Holomorphic Function Connected with the Collatz Problem

open access: yesNegative Values of a Holomorphic Function Connected with the Collatz Problem
Let F(z) be an entire holomorphic function connencted with the Collatz problem (See below 1). We show that the function F(z) satisfies an inequality -log(-x) < F(x) < 0 for all negative real number x smaller than -1, except integer.
