ON THE THEORY OF EPIGROUPS. I
L. N. Shevrin · Sbornik Mathematics · 1995
This is a continuation of an earlier paper with the same title. The results of the earlier paper are used to characterize epigroups that are decomposable into a semilattice of nil extensions of rectangular groups, into a band or semilattice of right Archimedean epigroups, or into a band, a semilattice, or a rectangular band of unipotent epigroups. Applications are made to epigroups in which the pseudoinversion operation is an endomorphism, and epigroups in which pseudoinversion is an antiendomorphism are characterized.Bibliography: 24 titles.
