关于反证法,牛顿说:“反证法是数学家最精当的武器之一。”这就充分肯定了这一方法的积极作用和不可动摇的重要地位。它在数学各个分支里都有广泛的应用,本文通过查阅各种有关反证法的参考文献,对反证法进行了系统的归纳总结,本文的目的是让人们更方便地深入学习认识反证法以及正确灵活地运用反证法。 On the law of proof, Newton said: “The law of proof is one of the most sophisticated weapons for mathematicians.” This fully affirmed the positive role of this method and its unshakable importance. It has a wide range of applications in all branches of mathematics. This paper systematically summarizes the anti-syndromes by referring to various references on the anti-syndromes. The purpose of this article is to make it easier for people to learn more about the law of anti-syndromes and to use them correctly and flexibly Proof of law.
