Nuprl Lemma : fpf_dom_compose_lemma
∀f,g,x,eq:Top. (x ∈ dom(g o f) ~ x ∈ dom(f))
Proof
Definitions occuring in Statement :
fpf-compose: g o f,
fpf-dom: x ∈ dom(f),
top: Top,
all: ∀x:A. B[x],
sqequal: s ~ t
Definitions unfolded in proof :
all: ∀x:A. B[x],
member: t ∈ T,
fpf-compose: g o f,
fpf-dom: x ∈ dom(f),
pi1: fst(t)
Latex:
\mforall{}f,g,x,eq:Top. (x \mmember{} dom(g o f) \msim{} x \mmember{} dom(f))
