Nuprl Lemma : evalall-atom2
∀[x:Atom2]. (evalall(x) ~ x)
Proof
Definitions occuring in Statement :
evalall: evalall(t),
atom: Atom$n,
uall: ∀[x:A]. B[x],
sqequal: s ~ t
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
uimplies: b supposing a,
evalall: evalall(t),
has-value: (a)↓,
sq_type: SQType(T),
all: ∀x:A. B[x],
implies: P ⇒ Q,
guard: {T},
subtype_rel: A ⊆r B,
or: P ∨ Q,
not: ¬A,
false: False,
outl: outl(x),
outr: outr(x)
