Lemmas in set theory

ID: lemmas-in-set-theory

In set theory, the term "lemma" generally refers to a proven statement or proposition that is used as a stepping stone to prove other statements or theorems. In mathematical writing, authors often introduce lemmas to break down complex proofs into smaller, more manageable pieces. A lemma may not be of primary interest in itself, but it helps to establish the truth of more significant results.
