## indifference

This metric is simply the total number of publications divided by the number of total number of citations (Egghe and Rousseau 1996); it was originally proposed to evaluate journalsbut can be applied to individuals as well. The larger this value, the more indifferent the community is to the author's work. This metric is also just the inverse of the mean number of citations per publication (C/P).

$$D=\frac{P}{C^P}$$
