Nuprl Lemma : classfun_wf
∀[Info,T:Type]. ∀[es:EO+(Info)]. ∀[X:EClass(T)]. ∀[e:E]. (X(e) ∈ T) supposing X is functional
Proof
Definitions occuring in Statement :
classfun: X(e),
es-functional-class: X is functional,
eclass: EClass(A[eo; e]),
event-ordering+: EO+(Info),
es-E: E,
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
member: t ∈ T,
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
uimplies: b supposing a,
es-functional-class: X is functional,
and: P ∧ Q,
es-total-class: es-total-class(es;X),
all: ∀x:A. B[x],
single-valued-classrel: single-valued-classrel(es;X;T),
classrel: v ∈ X(e),
single-valued-bag: single-valued-bag(b;T),
classfun: X(e),
eclass: EClass(A[eo; e]),
subtype_rel: A ⊆r B,
