Traduction de "deduction theorem" en français

A procedure for "discharging" assumptions from an inference, causing them to become antecedents of the conclusion; or vice versa. Symbolically, the conversion of an inference of the form P, A \vdash C to an inference of the form P \vdash A \rightarrow C or vice versa, where \vdash is the turnstile symbol. The validity of the procedure is a metatheorem of the given logical theory.
