Abstract: The structure of different types of time series in citation 
analysis is revealed, using an adapted form of the Frandsen-Rousseau 
notation. Special cases where this approach can be used include time 
series of impact factors and time series of h-indices, or h-type indices. 
This leads to a tool describing dynamic aspects of citation analysis. Time 
series of h-indices are calculated in some specific models. (C) 2008
