Modeling of the layer structure of infinte groups

Mathematical modeling of infinite discrete objects is possible if these objects satisfy any conditions of finiteness. If all the layers of elements in the group are finite, a functional description of the power of the layers for such a group is possible. A layer is a set of all elements of the group of the same order. For the first time the infinite layer-finite groups were investigated by S. N. Chernikov initially without a title, and then in his subsequent publications the name of layer-finite groups was fixed. The most intensive studies of the properties of layer-finite groups were carried out in the 1940s and 1950s by S. N. Chernikov, R. Baer, X. X. Muhammedzhan. The paper gives a functional description for some layer-finite groups. It is shown that primary layer-finite groups and layer-finite groups can be very well visualized in the case of two prime divisors of the orders of the elements of the group. For a primary case, it is convenient to use the usual graphical representation. In the case of two prime divisors of the orders of elements of a layer-finite group, visualization of the power functions of the layers by means of surfaces in three-dimensional space is carried out. For a larger number of simple order-divisors, an approach for modeling the layer structure of a complete layer-finite group using subgroup analysis is proposed. In this paper, we study the power functions of the layers for complete layer-finite groups and some finite extensions of these groups, and demonstrate their graphical representations.
