U+22AC "⊬" Does Not Prove Unicode Character

U+22AC "⊬" Does Not Prove is a mathematical symbol that represents the negation of a provability relation, typically indicating that a certain statement cannot be derived or proven from a given set of premises within a formal system. It is the logical counterpart to the "proves" symbol (⊢) and is used in fields such as proof theory, logic, and computer science to denote that no formal proof exists for a proposition under specified assumptions. Its appearance resembles a turnstile with a vertical line through it, visually negating the standard assertion sign, and it plays a key role in discussions of Gödel's incompleteness theorems and other metamathematical arguments.
