Nuprl Lemma : intdeq_reduce_lemma

∀y,x:Top.  (IntDeq x y ~ (x =z y))


Proof




Definitions occuring in Statement :  int-deq: IntDeq,  eq_int: (i =z j),  top: Top,  all: ∀x:A. B[x],  apply: f a,  sqequal: s ~ t
Definitions unfolded in proof :  all: ∀x:A. B[x],  member: t ∈ T,  int-deq: IntDeq
Lemmas referenced :  top_wf
Rules used in proof :  sqequalSubstitution,  sqequalTransitivity,  computationStep,  sqequalReflexivity,  lambdaFormation,  cut,  hypothesis,  lemma_by_obid,  sqequalRule

Latex:
\mforall{}y,x:Top.    (IntDeq  x  y  \msim{}  (x  =\msubz{}  y))
