Inverse of Heyting algebra morphism is p-morphism
$begingroup$
It is known that the category of Heyting algebras is dually equivalent to the category of Esakia spaces (which is equivalent to the category of descriptive intuitionistic Kripke frames). Under the duality, a Heyting morphism $f : H to H'$ is send to its inverse, that is it sends a prime filter in $H'$ to its inverse image.
Question: Why is this inverse map a p-morphism (or bounded morphism)?
All references I have found for this refer to a paper by Esakia himself, in Russian. I am looking for an English reference or a proof.

Check out Lemma 5.5 of Patrick Morandi's excellent notes on duality theory for distributive lattices and Heyting algebras.

I'd found them indeed. Thanks!

For a somewhat different type of argument you can also have a look at Theorem 6 of the paper Canonical extensions, Esakia spaces, and universal models by Mai Gehrke.
