Definition:Corresponding Conditional

Let $$p_1, p_2, p_3, \ldots, p_n \vdash q$$ be a sequent of propositional logic.

It can be expressed as a theorem as follows:


 * $$\vdash p_1 \implies \left({p_2 \implies \left({p_3 \implies \left({\ldots \implies \left({p_n \implies q}\right) \ldots }\right)}\right)}\right)$$

This is known as the sequent's corresponding conditional.

This is proved in the Extended Rule of Implication.
