h(2)-index

The h(2)-index (Kosmulski 2006) is similar to the h-index, but rather than define the core based on h publications having h citations, this index requires the h publications to each have h2 citations:

$$h\left(2\right)=\underset{i}{\max}\left(i^2 \leq C_i\right).$$

This leads to h(2) having a stricter definition of the core publications than many other metrics.

Example

Publications are ordered by number of citations, from highest to lowest.

Citations (Ci)42361411993222111000
Rank-squared (i2)149162536496481100121144169196225256
Rank (i)12345678910111213141516
h(2) = 3

The largest rank where i2Ci is 3.
