Bases for certain varieties of completely regular semigroups

Mario Petrich (2021)

Commentationes Mathematicae Universitatis Carolinae

Completely regular semigroups equipped with the unary operation of inversion within their maximal subgroups form a variety, denoted by 𝒞ℛ . The lattice of subvarieties of 𝒞ℛ is denoted by ( 𝒞ℛ ) . For each variety in an -subsemilattice Γ of ( 𝒞ℛ ) , we construct at least one basis of identities, and for some important varieties, several. We single out certain remarkable types of bases of general interest. As an application for the local relation L , we construct 𝐋 -classes of all varieties in Γ . Two figures illustrate...
