Unfortunately, the paper you cite is paywalled and not\n\u003e\n\u003e available at sci-hub, so I haven't read it.\n\nSorry for the paywalled link, without paywall you can read the article on Google Books preview:\n\nhttps://books.google.de/books?id=hbXsCgAAQBAJ\u0026pg=PA63\u0026source=gbs_toc_r#v=onepage\n\nI like your neat and simple proof idea for approximation preservation!\n\nCheers, Martin"}
