  3. 2. Diagonal Ranks of Semigroups

    University essay from Institutionen för matematik (MA)

    Author : Ilia Barkov; [2013]
    Keywords : semigroup; diagonal act; diagonal rank;

    Abstract : We introduce the notion of diagonal ranks of semigroups,which are numerical characteristics of semigroups. Some base propertiesof diagonal ranks are obtained. A new criterion for a monoidbeing a group is obtained using diagonal ranks.For some semigroup classes we investigate whether their diagonal acts are finitely generatedor not. READ MORE
