A semantic tableau is a proof system that provides a graphical method for determining the satisfiability of a set of formulas in propositional or first-order logic. This method systematically breaks down complex logical expressions into simpler components, allowing one to check whether a contradiction arises from assuming the negation of a statement. The tableau consists of branches that represent possible interpretations of the formulas, making it an effective tool in both automated theorem proving and manual proof construction.
