Nuprl Lemma : manames-overlap-nil
∀[x,y:Top]. ∀[nms:MaName List]. (if [] and nms overlap then x else y fi ~ y)
Proof
Definitions occuring in Statement :
manames-overlap-case: if nms1 and nms2 overlap then x else y fi,
MaName: MaName,
nil: [],
list: T List,
uall: ∀[x:A]. B[x],
top: Top,
sqequal: s ~ t
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
manames-overlap-case: if nms1 and nms2 overlap then x else y fi,
branch: if p:P then A[p] else B fi ,
subtype_rel: A ⊆r B,
all: ∀x:A. B[x],
so_lambda: λ2x.t[x],
so_apply: x[s],
prop: ℙ,
implies: P ⇒ Q,
decidable: Dec(P),
or: P ∨ Q,
not: ¬A,
false: False
Latex:
\mforall{}[x,y:Top]. \mforall{}[nms:MaName List]. (if [] and nms overlap then x else y fi \msim{} y)
