图书标签: 数学 SJC 戴德金 number 纸质 数论 数学编程与统计 数学史
Two most important essays by the famous German mathematician: one provides an arithmetic, rigorous foundation for the irrational numbers, thereby a rigorous meaning of continuity in analysis. The other is an attempt to give logical basis for transfinite numbers and properties of the natural numbers.
戴德金对无理数的纯算术方法推导。排列有理数用到了数轴。所以数轴不算一个geometrical intuition哦?然后从数轴这个line推断有理数是不连续的,它们的gap里面还有其他数即无理数。这个move不算stretching an analogy哦?

评分Continuity and Irrational numbers. 非常优美的策略。关键概念的征用来自解决问题的实际需要。数学气息>哲学气息。相当依赖geometric intuition.
