Lógica Intuicionista<br />

Lógica intuicionista<br />

Cálculo de secuentes intuicionista. Basta con modificar el caso<br />

clásico del siguiente modo:<br />

Los secuentes sólo tienen una fórmula al lado derecho Γ, α ⊢ β<br />

Cambiamos la regla<br />

Γ, α ⊢ ∆ Γ ′ , β ⊢ ∆ ′<br />

Γ, Γ ′ , α ∨ β ⊢ ∆, ∆ ′ ∨L<br />

por la nueva:<br />

Γ, α ⊢ ϕ Γ ′ , β ⊢ ϕ<br />

Γ, Γ ′ , α ∨ β ⊢ ϕ<br />

∨L<br />
