638:-index has been characterized in terms of three natural axioms by Woeginger (2008). The simplest of these three axioms states that by moving citations from weaker articles to stronger articles, one's research index should not decrease. Like the
398:
333:
422:-index only requires a minimum of n citations for the least-cited article in the set and thus ignores the citation count of very highly cited papers. Roughly, the effect is that
651:
462:-index saturates whenever the average number of citations for all published papers exceeds the total number of published papers; the way it is defined, the
39:
190:
344:
430:
allows citations from higher-cited papers to be used to bolster lower-cited papers in meeting this threshold. In effect, the
438:-index if a fixed number of citations can be distributed freely over a fixed number of papers. Therefore, in all cases
282:
183:
119:
136:
245:-index of 10 indicates that the top 10 publications of an author have been cited at least 100 times (10), a
