p-index (Prathap)
Also called the mock hm-index (Prathap 2010b), the p-index (Prathap 2010a) is derived from mathematical modeling of the relationship of increasing numbers of publications and citations. It is a function of the total number of citations and the average citations per paper,
$$p=\sqrt[3]{\frac{\left(C^P\right)^2}{P}}.$$History
