This is about the comment area of The continuity of $g\circ h$ and $h$, and $h$ surjective, imply the continuity of $g$?
As a not-very-obvious question, many lovely commenters leaves a lot of ideas and proof snippets in the comment area. However, they got (auto) deleted. All my notifications are deleted too.
Usually, the comments are moved to chat, and people can also read the comments if they want.
I wonder if we have an archive of comments for this question? Or if we can recover them in a chat?
