哥德布拉特編著的《超實講義》是一部講述非標準分析的入門教程,是由作者數年教學講義發展並擴充而成。具備基本分析知識的高年級本科生,研究生以及自學人員都可以**讀懂。非標準分析理論不僅是研究無限大和無限小的強有力的理論,也是一種截然不同於標準數學概念和結構的方法,*是新的結構,目標和證明的源泉,推理原理的新起點。書中是從超實數繫統開始,從非標準的角度講述單變量積分,分析和拓撲,著重強調變換原理作為一個重要的數學工具的重要作用。數學宇宙的講述為全面研究非標準方法論提供了基礎保證。*後一章著眼於應用,將這些理論應用於loeb測度理論及其與lebesgue 的一些關繫,ramsey 定理,p-進數的非標準結構和冪級數,boolean 代數的stone 表示定理的非標準證明和hahn-banach 定理。《超實講義》的*大特點盡早引入內集,外集,超有限集,以及集理論擴展方法,較常規的建立在超結構基礎上,這樣的方式*加顯而易見。 讀者對像:數學專業的高年級本科生,研究生和科研人員。
