《不等式》內容簡介：The first intention of this book， then， is to establish fundamental inequalities in this area． But more importantly， its purpose is to put them in context， and to show how useful they are． Although the book is very largely self—contained， it should therefore principally be of interest to analysts， and to those who use analysis seriously。
