Metrics description

h-index

A scientist has an h-index if h of his N publications are cited at least h times each, while the remaining (N - h) publications are cited no more than h times each.

https://www.pnas.org/doi/full/10.1073/pnas.0507655102

i10-index

The number of the author's publications that received at least 10 links each.

https://scholar.googleblog.com/2011/11/google-scholar-citations-open-to-all.html

m-index

The researcher's m-index is numerically equal to the ratio of his h-index to the number of years that have passed since the first publication.

https://harzing.com/publications/white-papers/reflections-on-the-h-index

o-index

The geometric mean of the h-index and the number of citations of the most cited article of the scientist.

https://arxiv.org/abs/1511.01545

g-index

For a given set of articles, sorted in descending order of the number of citations that these articles received, the g-index is the largest number such that the g most cited articles received (in total) at least g² citations.

https://doi.org/10.1007/s11192-006-0144-7

w-index

If w articles of a researcher have at least 10w citations each and other publications are less than 10(w+1) citations, then the researcher's w-index is equal to w.
