Higher-order π-calculus

Higher-order π-calculus is a mathematical framework used to model and analyze complex systems that involve communication. Unlike basic communication models that only send simple messages, it allows processes to send entire processes or functions as messages. This enables the representation of dynamic systems where components can change behavior or create new components during execution. Higher-order π-calculus is useful for understanding sophisticated interactions in distributed systems, programming languages, and network protocols, providing a precise way to describe how components can be created, transmitted, and modified during a system's operation.
