This study examines the almost periodic behavior of impulsive reaction-diffusion neural networks with conformable derivatives and distributed delays. New criteria ensure the existence and uniqueness of almost periodic states and global exponential stability.
Area of Science:
- Dynamical Systems and Control Theory
- Computational Neuroscience
- Mathematical Physics
Background:
- Reaction-diffusion neural networks are crucial for modeling complex spatio-temporal phenomena.
- Distributed delays and conformable derivatives introduce sophisticated dynamics.
- Impulsive perturbations represent sudden external influences.
Purpose of the Study:
- To investigate the qualitative behavior, specifically almost periodicity, of a reaction-diffusion neural network model.
- To analyze the global conformable exponential stability of the proposed network.
- To develop new analytical criteria for these dynamic properties.
Main Methods:
- A Lyapunov-based approach was employed for stability analysis.
- A novel Lyapunov-type function was constructed.
- Criteria for existence, uniqueness, and stability were mathematically derived.
Main Results:
- Sufficient conditions for the existence and uniqueness of an almost periodic state were established.
- The global conformable exponential stability of the network was analyzed.
- The findings extend existing results in the study of conformable models.
Conclusions:
- The research provides a robust framework for analyzing the dynamics of impulsive reaction-diffusion neural networks with conformable derivatives.
- The established criteria contribute to a deeper understanding of almost periodicity and stability in complex neural models.
- The study offers valuable insights for the design and control of such systems.

Propagation of Action Potentials
Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions.
