On some properties of even‐symmetric and odd‐symmetric dynamical systems

Abstract

Purpose

The purpose of this paper is to demonstrate new properties of continuous‐ and discrete‐time dynamical systems.

Design/methodology/approach

First, definitions of two types of spatial symmetry are introduced. These are used as definitions, which, along with existing knowledge show that it is possible to identify properties of dynamical systems that were previously unknown.

Findings

The main result of the paper is a new theorem regarding new properties of continuous‐ and discrete‐time dynamical systems.

Research limitations/implications

The present study provides a starting point for further research on the differences between continuous‐ and discrete‐time dynamical systems. This work builds on the definition of spatial symmetry.

Practical implications

The theorem proved in this paper and the new properties of dynamical systems can be used to introduce new methods of approximating continuous‐time dynamical systems by discrete‐time dynamical systems and vice versa. Such approaches can also be helpful in constructing chaotic sources to model noise.

Originality/value

This paper offers contributions to the broader discussion of differences between continuous‐ and discrete‐time dynamical systems. In particular, the paper supports the statement that many discrete‐time processes cannot be embedded into continuous ones.
