Title: Dynamical Instabilities Causes Extreme Events in a Brusselator Model
Speaker: S. V. Manivelan, Research scholar, Department of Physics, M. R. Government Arts College (Affiliated to Bharathidasan University), Mannargudi, India
The Brusselator model, a classic in the realm of chemical kinetics and reaction-diffusion systems, is known for its captivating array of dynamic behaviors. It unravels sustained oscillations, intricate pattern formation, and even chaotic phenomena. These qualities make it a vital tool for comprehending the intricate emergence of complex spatiotemporal patterns within reaction-diffusion systems. Here we found and studied the rich dynamic properties of Extreme Event in this chemical model. In a dynamical system, Extreme event refers to a rare and often unpredictable occurrence that significantly deviates from the system's typical behavior. These events can have far-reaching consequences and are of interest in various fields, including physics, chemistry, climate science, finance, and engineering. Hence we characterized the event by statistical techniques and have delved further into studying their mechanics to explore system instability that causes the Extreme Event.
