在某一特定学科中，各分支学科的引文数量变化是已知的，但很少有系统的研究。本文比较了不同数学学科获奖数学家的引文数量。在同行评估方面，数学家们被选择在大致相等的小组中进行研究，这种评估是通过授予主要奖项和资助来进行的：古根海姆奖学金、斯隆奖学金和国家科学基金会职业补助金。我们发现了一种模式，即在某些分支学科工作的数学家比获得同一奖项的其他数学家被引用的次数少，这种模式对所有奖项都是一致的。因此，即使在学科层面对不同学科的总体被引率进行调整后，不同子学科的被引数也与同行评价不匹配。人口统计和雇佣数据为数学提供了一个讨论原因和解释的背景。
Variation of citation counts by subdisciplines within a particular discipline is known but rarely systematically studied. This paper compares citation counts for award-winning mathematicians is different subdisciplines of mathematics. Mathematicians were selected for study in groups of rough equivalence with respect to peer evaluation, where this evaluation is given by the awarding of major prizes and grants: Guggenheim fellowships, Sloan fellowships, and National Science Foundation CAREER grants. We find a pattern in which mathematicians working in some subdisciplines have fewer citations than others who won the same award, and this pattern is consistent for all awards. So even after adjustment at the discipline level for different overall citation rates for disciplines, citation counts for different subdisciplines do not match peer evaluation. Demographic and hiring data for mathematics provides a context for a discussion of reasons and interpretations.
