Skew group algebras and their Yoneda algebras
Mathematical Journal of Okayama University, 2001The paper is almost self contained, some necessary statements are reviewed. The nature of the work is such that in some parts there are various isomorphisms and rings to deal with. The two principal theorems of the paper are the following: Theorem 13.

Group theory and the theory of relations are used to study the kinship of certain kinds of primitive societies. It will be shown that these societies partition their members into classes that are permuted by the relations “class X has fathers (mothers) in class Y” so as to form a regular permutation group.

In his paper 'Theorie der Z6pfe' E. Artin' presented a theory of braids based on a study of their projections on a two-dimensional plane. In the projection each strand of a braid appears as a line, vertical in general, but at certain levels two neighboring strands interchange position, one strand crossing in front of the other one.
