Pi Calculus

Pi Calculus is a mathematical framework for modeling and analyzing how complex systems communicate and interact dynamically. It captures processes that can send and receive messages through communication channels, which can themselves be created or changed during interactions. Think of it like a flexible conversation system where participants can establish new links on the fly, enabling features like mobile communication. Used mainly in computer science, Pi Calculus helps understand the behavior of distributed, concurrent, and networked systems, providing formal tools to reason about their structure, connectivity, and evolution over time.
