Nuprl Lemma : pisend-var_wf

∀[v:pi_prefix()]. pisend-var(v) ∈ Name supposing ↑pisend?(v)


Proof




Definitions occuring in Statement :  pisend-var: pisend-var(v),  pisend?: pisend?(v),  pi_prefix: pi_prefix(),  name: Name,  assert: ↑b,  uimplies: b supposing a,  uall: ∀[x:A]. B[x],  member: t ∈ T
Lemmas :  pi_prefix-ext,  eq_atom_wf,  bool_wf,  eqtt_to_assert,  assert_of_eq_atom,  subtype_base_sq,  atom_subtype_base,  eqff_to_assert,  equal_wf,  bool_cases_sqequal,  bool_subtype_base,  assert-bnot,  neg_assert_of_eq_atom,  assert_wf,  pisend?_wf,  pi_prefix_wf

Latex:
\mforall{}[v:pi\_prefix()].  pisend-var(v)  \mmember{}  Name  supposing  \muparrow{}pisend?(v)
