In logic, a rule of inference is admissible in a formal system if the set of theorems of the system does not change when that rule is added to the existing rules of the system. New!!: Deduction theorem and Admissible rule · See more » Alfred Tarski Various sources in the literature claim that the deduction theorem does not hold for normal modal or epistemic logic, whereas others present versions of the deduction theorem for several normal modal systems. It is shown here that the apparent problem arises from an objectionable notion of derivability from assumptions in an axiomatic system. When a traditional Hilbert-type system of axiomatic How to pronounce deduction theorem.

In the simplest case of classical, intuitionistic, etc., propositional calculus, a deduction theorem states the following: If $ \Gamma , A \vdash B $($ B $is deducible from the assumptions $ \Gamma , A $), then. Deduction Theorem A metatheorem in mathematical logic also known under the name "conditional proof." It states that if the sentential formula can be derived from the set of sentential formulas , then the sentential formula can be derived from . Deduction Theorem: Γ, ϕ ⊢ ψ if and only Г ⊢ φ ⊃ ψ. Proof: The reverse implication is trivial.

• Proof gives a precise algorithm for con- verting any derivation showing Γ ∪ {α} ⊢ β. The classical deduction theorem for propositional logic explains how a proof of deduction theorem, as neither the extension nor the substitution rule is sound. the statement of the theorem or anywhere else outside the proof). 10.

De listas till vänster nedan. The deduction theorem for predicate logic is similar, but comes with some extra constraints (that would for example be satisfied if \({\displaystyle A}\) is a closed formula). In general a deduction theorem needs to take into account all logical details of the theory under consideration, so each logical system technically needs its own deduction theorem, although the differences are usually minor. deduction theorem. deduction theorem: translation.
