The ⊧ (Models) symbol is a mathematical operator frequently used in formal logic, model theory, and computer science. It consists of a single vertical bar with a double horizontal line and typically represents semantic entailment, meaning a specific structure satisfies a given set of axioms. While rarely seen in casual conversation, it is an essential piece of notation for mathematicians writing formal proofs.
