On the relationship between citations of publication output and Hirsch index h of authors: conceptualization of tapered Hirsch index h(T), circular citation area radius R and citation acceleration a.

ABSTRACT: The nature of the empirical proportionality constant A in the relation L = Ah(2) between total number of citations L of the publication output of an author and his/her Hirsch index h is analyzed using data of the publication output and citations for six scientists elected to the membership of the Royal Society in 2006 and 199 professors working in different institutions in Poland. The main problem with the h index of different authors calculated by using the above relation is that it underestimates the ranking of scientists publishing papers receiving very high citations and results in high values of A. It was found that the value of the Hirsch constant A for different scientists is associated with the discreteness of h and is related to the tapered Hirsch index h(T) by A(1/2) ≈ 1.21h(T).
