Nuprl Lemma : dlattice-eq-equiv

[X:Type]. EquivRel(X List List;as,bs.dlattice-eq(X;as;bs))


Proof




Definitions occuring in Statement :  dlattice-eq: dlattice-eq(X;as;bs) list: List equiv_rel: EquivRel(T;x,y.E[x; y]) uall: [x:A]. B[x] universe: Type
Definitions unfolded in proof :  uall: [x:A]. B[x] equiv_rel: EquivRel(T;x,y.E[x; y]) and: P ∧ Q refl: Refl(T;x,y.E[x; y]) all: x:A. B[x] dlattice-eq: dlattice-eq(X;as;bs) cand: c∧ B member: t ∈ T sym: Sym(T;x,y.E[x; y]) implies:  Q prop: trans: Trans(T;x,y.E[x; y])
