In linear algebra, a lemma is a proven statement or proposition that is used as a stepping stone to prove larger or more complex theorems. Lemmas often simplify the process of proving more substantial results by breaking them down into manageable components. Here are a few key points regarding lemmas in linear algebra: 1. **Purpose**: Lemmas are typically used to establish intermediate results that help in the proof of a main theorem.
