Left quasi r-wide semigroups with special bands formed by idempotent element sets

  • Left quasi r-wide semigroups with special bands formed by idempotent element sets is defined, The congruences on left quasi r-wide semigroups are characterized using correlation bands and (*,~)-Green's relations, and the related properties of left quasi r-wide semigroups are given.
