## p-Chain – Road To Zorn’s Lemma Part 1

Hello, infinite-set reader. Set theory is back. Starting this post, we’ve entered about Zorn’s Lemma. This discussion will start from several definitions and theorems that later lead to Zorn’s Lemma. Today we will learn about p-chain. Happy reading. p-Chain For any poset it is not guaranteed that every non-empty well ordered subset has an upper
