o-index
The o-index (Dorogovtsev and Mendses 2015) was designed to balance a researcher's most-cited work with their diligence in regular publication, and is simply the geometric mean of their h-index and the count of citations to their most cited work. It is calculated as:
$$o=\sqrt{hC_{max}}.$$History
