Nuprl Lemma : set_lt_irreflexivity

[s:QOSet]. ∀[a:|s|].  False supposing a <a


Proof




Definitions occuring in Statement :  qoset: QOSet set_lt: a <b set_car: |p| uimplies: supposing a uall: [x:A]. B[x] false: False
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T uimplies: supposing a false: False not: ¬A implies:  Q prop: qoset: QOSet dset: DSet
