On the strong isomorphism of groups and isomorphism of $P$-symmetries. (Russian)

Authors: Zamorzaev A. M.


The concept of strong isomorphism of groups is introduced that gives conditions when the number of different $Q$-middle groups of $P$-symmetry and the number of different junior groups of $P_0$-symmetry coincide. With using the strong isomorphism the concept of isomorphism of $P$-symmetries is made more precise.
