Abstract: General results on transformations on information production 
processes (IPPs), involving transformations of the h-index and related 
indices, are applied in concrete, simple cases: doubling the production 
per source, doubling the number of sources, doubling the number of sources 
but halving their production, halving the number of sources but doubling 
their production (fusion of sources) and, finally, special cases of 
general power law transformations. In each case we calculate concrete 
transformation formulae for the h-index h (transformed into h*) and we 
discuss when we have h* < h, h* = h or h* > h. These results are then 
extended to some other h-type indices such as the g-index, the R-index and 
the weighted h-index. (C) 2007 Elsevier Ltd. All rights reserved.
