内容简介

　　This is primarily a textbook on mathematical analysis for graduate students in economics. While there are a large number of excellent textbooks on this broad topic in the mathematics literature， most ofthese texts are overly advanced relative to the needs of the vast majority of economics students and concentrate on various topics that are not readily helpful for studying economic theory. Moreover， it seems that most economics students lack the time or courage to enroll in a math course at the graduate level. Sometimes this is not even for bad reasons， for only few math departments offer classes that are designed for the parhcular needs of economists. Unfortunately，more often than not， the consequent lack ofmathematical background cre-ates problems for the students at a later stage of their education， since an exceedingly large fraction ofeconomic theory is impenetrable without some rigorous background in real analysis. The present text aims at providing a remedy for this inconvenient situation.

怎么说呢！看完这本书，估计能了解实分析，但并不真正理解。高雅点说，是飘渺。不高雅点说，是隔靴搔痒。

就是太厚了，800页呢。

看了20页，感觉写得不够友好。这书不太适合自学，必须有老师教才行。
