Return-to-home model for short-range human travel

Area of Science:

• Mathematical modeling
• Population dynamics
• Epidemiology

Background:

• Understanding individual movement patterns is crucial for predicting population dynamics.
• Existing models often simplify or omit the 'return home' behavior, which can significantly impact spatial distributions.
• Incorporating realistic movement behaviors is essential for accurate ecological and epidemiological simulations.

Purpose of the Study:

• To develop a novel mathematical model for local individual movement incorporating the 'return home' phenomenon.
• To analyze the long-term behavior of solutions within this mathematical framework.
• To extend the model to include colonization processes and its application to epidemic modeling.

Main Methods:

• Development of a mathematical framework to describe individual movement with home-return.
• Analysis of the large-time asymptotic behavior of the model's solutions.
• Extension of the model to incorporate colonization and epidemic spread dynamics.

Main Results:

• The study establishes a functional framework for modeling movement with home-return.
• Analysis reveals the long-term dynamics of individual movement patterns.
• The model is successfully extended to simulate colonization and epidemic spread.

Conclusions:

• The developed mathematical model accurately captures individual movement, including the return home behavior.
• The extended model provides a valuable tool for studying colonization and epidemic dynamics.
• This work offers a foundation for more realistic simulations in population dynamics and epidemiology.
