Let W be the permutational wreath product of two groups A and B.In this paper, we study the relationship between the semicompleteness of W and the semicompleten
In this paper, we introduce the concept of refined semilattices of semigroups. This is a modified concept of the generally strong semilattice of semigroups init
A cover for a finite group is a set of proper subgroups whose union is the whole group. For a finite group G, we denote by σ(G) the least positive integer n su
The classification of homogeneous integral table algebras of degree λ> 2 with a standard real faithful basis element of width 2 has been done. In this paper, we
