Nuprl Lemma : ident_trans_ap_lemma
∀A,F,D,C:Top. (identity-trans(C;D;F) A ~ cat-id(D) (F A))
Proof
Definitions occuring in Statement :
identity-trans: identity-trans(C;D;F),
functor-ob: ob(F),
cat-id: cat-id(C),
top: Top,
all: ∀x:A. B[x],
apply: f a,
sqequal: s ~ t
Definitions unfolded in proof :
identity-trans: identity-trans(C;D;F),
all: ∀x:A. B[x],
member: t ∈ T,
top: Top,
