1977年,为考查一年级的博士研究生是否已经成功掌握为攻读数学博士学位所需的基本数学知识和技能,加州大学伯克利分校数学系设立了一项书面考试,作为获得博士学位的首要要求之一。该项考试自其创设以来,已成为研究生获得博士学位必须克服的一个主要障碍。本书的目的即为出版这些考试材料,以期对本科生准备该项考试有所帮助。《BR》 全书收录*近25年的1250余道伯克利数学考试试题,对所有计划攻读数学博士学位的学生,本书中的试题和解答都颇具价值,读者研读完本书,在诸如实分析、多变量微积分、微分方程、度量空间、复分析、代数学及线性代数等学科的解题能力都将得到提高。《BR》 这些问题按学科及难易程度编排,每道试题均注明相应的考试年月,读者可以依此方便地整理由各套试题。附录介绍如何得到电子版试题,考试大纲以及各次考试的及格线。《BR》 新版已包含直至2003秋季学期的*近考试试题和解答,增添了以前版本未收录的许多新的试题及题解。
