Pous Index

The Pous index is one of the many quantitative tools used to evaluate the quality of a researcher's works.
It is defined as the length of the smallest author chain reaching Damien Pous for the copublication relation (very similar to the Erdös number , yet using Damien Pous instead of Paul Erdös).
A useful website for computing one's own Pous index, (as well as a great number of other indices).
