Nuprl Lemma : proj-eq-equiv

[n:ℕ]. EquivRel(ℙ^n;a,b.a b)


Proof




Definitions occuring in Statement :  proj-eq: b real-proj: ^n equiv_rel: EquivRel(T;x,y.E[x; y]) nat: uall: [x:A]. B[x]
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T 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] proj-eq: b real-proj: ^n real-vec: ^n uimplies: supposing a nat: cand: c∧ B sym: Sym(T;x,y.E[x; y]) implies:  Q prop: trans: Trans(T;x,y.E[x; y]) so_lambda: λ2x.t[x] so_apply: x[s] ge: i ≥  decidable: Dec(P) or: P ∨ Q not: ¬A satisfiable_int_formula: satisfiable_int_formula(fmla) exists: x:A. B[x] false: False top: Top squash: T uiff: uiff(P;Q) iff: ⇐⇒ Q so_lambda: λ2y.t[x; y] so_apply: x[s1;s2] rev_implies:  Q rev_uimplies: rev_uimplies(P;Q)
