Known as the , it signifies a relation of syntactic consequence—the idea that a conclusion can be derived from a set of premises within a specific proof system. This article explores the multi-faceted roles of the symbol, its distinction from the double turnstile ( ), and its applications in modern logic and programming. 1. The Syntactic Foundation: What Represents In formal logic, the expression
