Functional Dynamics II : Syntactic Structure

TL;DR

This paper analyzes the hierarchical and recursive nature of functional dynamics, revealing how complex, multi-level maps can generate meta-chaos and relate to biological and linguistic syntax formation.

Contribution

It introduces a hierarchical framework for functional dynamics, demonstrating how recursive meta-maps can produce complex behaviors like meta-chaos and linking these to biological and language systems.

Findings

Hierarchical meta-maps generate complex, recursive dynamics.

Piecewise-linear maps can embed arbitrary one-dimensional maps.

Meta-chaos exhibits stronger orbital instability than exponential.

Abstract

Functional dynamics, introduced in a previous paper, is analyzed, focusing on the formation of a hierarchical rule to determine the dynamics of the functional value. To study the periodic (or non-fixed) solution, the functional dynamics is separated into fixed and non-fixed parts. It is shown that the fixed parts generate a 1-dimensional map by which the dynamics of the functional values of some other parts are determined. Piecewise-linear maps with multiple branches are generally created, while an arbitrary one-dimensional map can be embedded into this functional dynamics if the initial function coincides with the identity function over a finite interval. Next, the dynamics determined by the one-dimensional map can again generate a `meta-map', which determines the dynamics of the generated map. This hierarchy of meta-rules can continue recursively. It is also shown that the dynamics can produce `meta-chaos' with an orbital instability that is stronger than exponential. The relevance of the generated hierarchy to biological and language systems is discussed, in relation with the formation of syntax of a network.
