Two Dimensional Discrete Dynamics of Integral Value Transformations

Abstract

A notion of dimension preservative map, \textit{Integral Value Transformations} (IVTs) is defined over ${\mathbb{N}}^k$ using the set of $p$-adic functions. Thereafter, two dimensional \textit{Integral Value Transformations} (IVTs) is systematically analyzed over $\mathbb{N}\times \mathbb{N}$ using pair of two variable Boolean functions. The dynamics of IVTs over $\mathbb{N}\times \mathbb{N}={\mathbb{N}}^2$ is studied from algebraic perspective. It is seen that the dynamics of the IVTs solely depends on the dynamics (state transition diagram) of the pair of two variable Boolean functions. A set of sixteen \textit{Collatz-like} IVTs are identified in two dimensions. Also, the dynamical system of IVTs having attractor with one, two, three and four cycles are studied. Additionally, some quantitative information of \textit{Integral Value Transformations} (IVTs) in different bases and dimensions are also discussed.
