Nuprl Lemma : eclass1-disjoint-classrel
∀[Info,A,B,C:Type]. ∀[Y:EClass(A)]. ∀[X:EClass(B)]. ∀[f:Id ⟶ B ⟶ C]. ∀[es:EO+(Info)].
(disjoint-classrel(es;B;X;A;Y) ⇒ disjoint-classrel(es;C;(f o X);A;Y))
Proof
Definitions occuring in Statement :
eclass1: (f o X),
disjoint-classrel: disjoint-classrel(es;A;X;B;Y),
eclass: EClass(A[eo; e]),
event-ordering+: EO+(Info),
Id: Id,
uall: ∀[x:A]. B[x],
implies: P ⇒ Q,
function: x:A ⟶ B[x],
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
implies: P ⇒ Q,
disjoint-classrel: disjoint-classrel(es;A;X;B;Y),
all: ∀x:A. B[x],
member: t ∈ T,
or: P ∨ Q,
not: ¬A,
false: False,
uiff: uiff(P;Q),
and: P ∧ Q,
uimplies: b supposing a,
squash: ↓T,
exists: ∃x:A. B[x],
prop: ℙ,
so_lambda: λ2x.t[x],
