PROGRAM
TIPPING POINTS IN COMPLEX SYSTEMS (HYBRID)

ORGANIZERS:
Partha Sharathi Dutta (IIT Ropar, India), Vishwesha Guttal (IISc, India), Mohit Kumar Jolly (IISc, India) and Sudipta Kumar Sinha (IIT Ropar, India)
DATE: 19 September 2022 to 30 September 2022
VENUE: Ramanujan Lecture Hall and Online

Complex systems are seen across various branches of science; examples include climatic systems, financial markets, systems biology, and ecosystems. Many new techniques have emerged for understanding the dynamics of complex systems and predicting their long-term behavior, which are often obscured by apparent randomness and disorder. Nevertheless, these systems can undergo abrupt, large, and often irreversible changes to the system's state that have wide-ranging implications. When a dynamical system is tipped to a contrasting state in a relatively short period under the influence of small stochastic perturbations; this phenomenon is called a critical-transition or tipping. In the last two decades there are significant developments in the studies of tipping. This workshop will cover all the three major types of tipping; B-tipping, N-tipping and R-tipping, and will also discuss the recent advances on tipping point research including the application of machine learning.

The meeting aims to bring together ecologists, climate scientists, and dynamical system theorists, or in related fields who have contributed substantially to the field for catalyzing constructive discussions that can lead to further advancements of this subject and identify exciting and unexplored areas.
