Nuprl Lemma : strict4_wf
∀[F:Base]. (strict4(F) ∈ ℙ)
Proof
Definitions occuring in Statement :
strict4: strict4(F),
uall: ∀[x:A]. B[x],
prop: ℙ,
member: t ∈ T,
base: Base
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
strict4: strict4(F),
prop: ℙ,
and: P ∧ Q,
so_lambda: λ2x.t[x],
implies: P ⇒ Q,
so_apply: x[s],
all: ∀x:A. B[x],
or: P ∨ Q
