Nuprl Lemma : pipar?_wf

[v:pi_term()]. (pipar?(v) ∈ 𝔹)


Proof




Definitions occuring in Statement :  pipar?: pipar?(v) pi_term: pi_term() bool: 𝔹 uall: [x:A]. B[x] member: t ∈ T
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T ext-eq: A ≡ B and: P ∧ Q subtype_rel: A ⊆B all: x:A. B[x] implies:  Q bool: 𝔹 unit: Unit it: btrue: tt uiff: uiff(P;Q) uimplies: supposing a sq_type: SQType(T) guard: {T} eq_atom: =a y ifthenelse: if then else fi  pizero: pizero() pipar?: pipar?(v) pi1: fst(t) bfalse: ff exists: x:A. B[x] prop: or: P ∨ Q bnot: ¬bb assert: b false: False picomm: picomm(pre;body) pioption: pioption(left;right) pipar: pipar(left;right) pirep: pirep(body) pinew: pinew(name;body)
