I recommend writing “uses” of modules/theories/libraries into your HOL script
and copying those into your interactive HOL sessions with M-h M-r.
A “use” is either an open declaration or the use of a qualified name. For
example, writing fooTheory.bar_def and then using M-h M-r on that string wil
Thanks, my problem has been resolved using inductions.
I'm actually using extrealTheory. All I have for the necessary and
sufficient condition of a suminf being PosInf is the following:
[ext_suminf_eq_infty] Theorem
⊢ ∀f.
(∀n. 0 ≤ f n) ∧ (∀e. e < PosInf ⇒ ∃n. e ≤ ∑ f (count
