Spatiotemporal representation of long-delayed systems: An alternative approach

Area of Science:

• Nonlinear Dynamics
• Complex Systems
• Theoretical Physics

Background:

• Dynamical systems with long delays can exhibit complex temporal phenomena.
• These phenomena can resemble spatiotemporal behavior when represented in a 2D space.
• Existing normal forms methods for these systems have limitations in variable interpretation.

Purpose of the Study:

• To extend a recently proposed alternative approach for interpreting variables in long-delayed dynamical systems.
• To apply this new interpretation to paradigmatic examples.
• To facilitate a rethinking of spatiotemporal representations for delayed systems.

Main Methods:

• Utilizing an alternative interpretation of variables in long-delayed dynamical systems.
• Applying normal forms description based on the enhanced variable interpretation.
• Analyzing paradigmatic examples to validate the extended approach.

Main Results:

• The extended approach offers a more physically grounded interpretation of system variables.
• This interpretation simplifies the determination of normal forms for delayed systems.
• Successful application to paradigmatic examples demonstrates the approach's utility.

Conclusions:

• The proposed extension provides a more intuitive and effective framework for spatiotemporal representation of long-delayed systems.
• This work paves the way for a revised understanding of how to analyze and represent complex dynamics in such systems.
• The findings encourage further exploration of this approach in various scientific domains.
