Cellular Rings and Groups of Automorphisms of Graphs

Abstract

The present part of the book consideres the following questions: construction and description of the centralizer ring of a given permutation group; enumerating the cellular subrings of a given cellular ring; determining the automorphism group of a cellular ring; finding those cellular rings which are centralizer rings of a suitable permutation group; computer implementation of developed algorithms for computing in cellular rings and methodology for utilizing these programms.\par There is a special chapter which includes a survey of results obtained by Soviet mathematicians who used the technique described above.
