Nuprl Lemma : es-fix-cases
∀[es,f,e:Top]. (f**(e) ~ if e = f e then e else f**(f e) fi )
Proof
Definitions occuring in Statement :
es-fix: f**(e),
es-eq-E: e = e',
ifthenelse: if b then t else f fi ,
uall: ∀[x:A]. B[x],
top: Top,
apply: f a,
sqequal: s ~ t
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
es-fix: f**(e),
fix: f**(x),
ycomb: Y,
es-eq-E: e = e',
eqof: eqof(d)
Latex:
\mforall{}[es,f,e:Top]. (f**(e) \msim{} if e = f e then e else f**(f e) fi )
