Nuprl Lemma : parallel-class-bind-left

∀[Info,T,S:Type]. ∀[X,Y:EClass(T)]. ∀[Z:T ─→ EClass(S)].  (X || Y >t> Z[t] = X >t> Z[t] || Y >t> Z[t] ∈ EClass(S))


Proof




Definitions occuring in Statement :  parallel-class: X || Y,  bind-class: X >x> Y[x],  eclass: EClass(A[eo; e]),  uall: ∀[x:A]. B[x],  so_apply: x[s],  function: x:A ─→ B[x],  universe: Type,  equal: s = t ∈ T
