基本数学概念的探讨与改革
首发时间:2010-10-19
摘要:哥德尔不完全定理说明:形式逻辑无法建立无矛盾的数学体系;唯物辩证法是阐述基本数学概念的必要方法.数学上的基本术语几乎都是理想性的事物,理想依赖于现实.无穷集合是有穷集合序列的极限,而且这个极限具有不可达到的性质.无尽小数、无穷大、无穷小的真实意义都是无穷数列.线段长度的真值是误差界趋向于零时的极限;理想实数是以有理数为项的无穷序列的极限;无有大小的理想点是有大小的近似点的极限;理想平行线是近似平行线的极限;所有上述极限都具有不可达到的性质.瞬时速度的真实意义是足够小时段上的平均速度的足够准的近似值.满足误差界的近似方法与逐次逼近法是研究连续性现实数量的根本方法。

The Inquisition and Reformation on Fundamental Mathematics Concept
Abstract:The formalist logic could not make mathematics system possessed consistency. Materialist dialectics is necessary method to explain mathematics concept. The fundamental terminologies in mathematics are all almost the ideal object. Ideal objects are all depended on the existence. Infinite set is the limit of infinite sequence of finite set, and the limit possesses the nature of it could not be reached. The true sense of infinite decimal, infinity, and infinitesimal are all the infinite sequence. The true value of length of line segment is the limit of approximate value sequence, where error bounds tend to 0. The ideal real number is the limit of rational number sequence; the ideal point is the limit of approximate point sequence; the ideal parallel line is the limit of approximate parallel line sequence; and the above limits possess all the nature of it could not be reached. The true sense of twinkling velocity is sufficiently exactly approximate value of average value on sufficiently small time segment. The approximation method satisfied error bounds condition and the method approached step by step are fundamental method to settle continuous real quantity.
Keywords: Infinity Infinite set Point Real number Parallel line Mathematical induction excluded middle The infinity nature to cut segment of time and line
