Nuprl Lemma : rtermMultiply-right_wf

[v:rat_term()]. rtermMultiply-right(v) ∈ rat_term() supposing ↑rtermMultiply?(v)


Proof




Definitions occuring in Statement :  rtermMultiply-right: rtermMultiply-right(v) rtermMultiply?: rtermMultiply?(v) rat_term: rat_term() assert: b uimplies: supposing a uall: [x:A]. B[x] member: t ∈ T
Definitions unfolded in proof :  uall: [x:A]. B[x] uimplies: supposing a 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) sq_type: SQType(T) guard: {T} eq_atom: =a y ifthenelse: if then else fi  rtermMultiply?: rtermMultiply?(v) pi1: fst(t) assert: b bfalse: ff false: False exists: x:A. B[x] or: P ∨ Q bnot: ¬bb rtermMultiply-right: rtermMultiply-right(v) pi2: snd(t)
