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.
