The generalized tetration, defined by the equation F(z+1) = bF(z) in the complex plane with F(0) = 1, is considered for any b > e1/e. By comparing other solutions to Kneser’s solution, natural conditions are found which force Kneser’s solution to be the unique solution to the equation. This answers a conjecture posed by Trappmann and Kouznetsov. Also, a new iteration method is developed which numerically approximates the function F(z) with an error of less than 10−50 for most bases b, using… 
Tetration for complex bases
The tetration, defined by the equation F(z + 1) = bF(z) in the complex plane with F(0) =‬1, for the case where b is complex, is considered.
Constructing a hyperoperation sequence-pisa hyperoperations
In the context of other hyperoperation sequences, a new sequence of operations is constructed. A review of its properties reveals dependences between pairs of numbers, and so the sibling numbers are
Extension of tetration to real and complex heights
The continuous tetrational function r = τ(r, x), the unique solution of equation τ(r, x) = r and its differential equation τ (r, x) = qτ(r, x)τ (r, x − 1), is given explicitly as r = exp r [{x}]q,


Solution of F(z+1)=exp(F(z)) in complex z-plane
Robusts of the convergence and smallness of the residual indicate the existence of unique tetration F(z), that grows along the real axis and approaches L along the imaginary axis, being analytic in the whole complex z-plane except for singularities at integer the z ― 1 and the cut at z < ―2.
Finding the natural solution to $f(f(x)) = \exp(x)$
In this paper, we study the fractional iterates of the exponential function.  This is an unresolved problem, not due to a lack of a known solution, but because there are an infinite number of
On analytic iteration
where f/$(s) are polynomials in s. If the set S is the set of all integers, F (S , Z) is said to be the integer iterate of F(z). If the set S is the set of all real numbers, F (S , Z) is said to be

The exponential of iteration of ^{}-1
We study the mapping properties of a nonconstant entire solution of the equation f(z + 1) = ef(z) 1.
Uniqueness of holomorphic Abel functions at a complex fixed point pair
We give a simple uniqueness criterion (and some derived criteria) for holomorphic Abel functions and show that Kneser’s real analytic Abel function of the exponential is subject to this criterion.
Elementary numerical analysis
This chapter discusses Taylor Polynomials, Numerical Linear Algebra, and the Finite Difference Method for PDEs, as well as other topics of interest to students of mathematics.
Infinitely differentiable generalized logarithmic and exponential functions
We construct infinitely differentiable solutions of the functional equation f(x + 1) = ef(x). Numerical values are found and their accuracy is discussed.
