Nuprl Lemma : disjoint-union-comb_wf

[Info,A,B:Type]. ∀[X:EClass(A)]. ∀[Y:EClass(B)].  (X (+) Y ∈ EClass(A B))


Proof




Definitions occuring in Statement :  disjoint-union-comb: (+) Y eclass: EClass(A[eo; e]) uall: [x:A]. B[x] member: t ∈ T union: left right universe: Type

Latex:
\mforall{}[Info,A,B:Type].  \mforall{}[X:EClass(A)].  \mforall{}[Y:EClass(B)].    (X  (+)  Y  \mmember{}  EClass(A  +  B))
