论文摘要
证明封闭有限生成的凸锥通常被认为是Farkas引理几何证明中最困难的部分。我们提供了一个简单的简单证明，证明了这一事实，并且（为了完整）使用众所周知的论点从中得出了Farkas的引理。
Proving that a finitely generated convex cone is closed is often considered the most difficult part of geometric proofs of Farkas' lemma. We provide a short simple proof of this fact and (for completeness) derive Farkas' lemma from it using well-known arguments.
