whereas there is an exact linear relation between the wiener indices of kenograms and plerograms of isomeric alkanes, the respective terminal wiener indices exhibit a completely different behavior: correlation between terminal wiener indices of kenograms and plerograms is absent, but other regularities can be envisaged. in this article, we analyze the basic properties of terminal wiener indices...

The main differences between symbolic and morphic formal systems: Instead of the Kleene star for the symbolic universes, morphic universes are generated by the Stirling cross. Symbolic substitution and concatenation is preserving production concatenation. Morphic substitution/concatenation is opening up a system of interactive complexions of derivations. Comparison of substitution based product...
