Theorem: LO.Propositional.Superintuitionistic.Formula.Kripke.Satisfies.imp_def (Logic/Propositional/Superintuitionistic/Kripke/Semantics.lean)

State before:
α : Type u_1
inst✝ : Inhabited α
M : Model α
w : M.World
p q : Formula α
⊢ Satisfies M w (p ⟶ q) ↔ ∀ {w' : M.Frame.World}, w ≺ w' → Satisfies M w' p → Satisfies M w' q
Tactic:
simp [Satisfies, imp_iff_not_or]
