Hirsch 指数研究的新进展

A precise definition of the discrete Hirsch index (h-index for short) is given and the notion of a Hirsch core is introduced.The concept of a h-index is generalized to a real-valued setting.Definitions and examples are given of some other generalizations of the h-index,namely the g-index and the A-index.It is concluded that the h-index and the g-index taken together present a concise picture of a scientist's achievements in terms of publications and citations.
