Abstract: Basic publication-citation matrices are used to calculate 
informetric indicators such as journal impact factors or R-sequences. 
Transforming these publication-citation matrices clarifies the 
construction of other indicators. In this article, some transformations 
are highlighted together with some of their invariants. Such invariants 
offer a rigorous mathematically founded way of comparing informetric 
matrices before and after a transformation. (c) 2007 Elsevier Ltd. All
