Unraveling the dynamics of growth, aging and inflation for citations to scientific articles from specific research fields

作者：

Highlights：

• Inflation-adjusted citation rates separate into independent growth and aging parts.

• Normalizing by journal-specific article-publication rates accounts for inflation.

• The citation-number-dependent growth exhibits superlinear preferential attachment.

• Obsolescence-induced aging is an exponential function of time in the long term.

• Growth and aging parameters show interesting variations between research fields.
