  • On the le-semigroups whose semigroup of bi-ideal elements is a normal band 
    Bhuniya, A.K.; Kumbhakar, M. (Algebra and Discrete Mathematics, 2015)
    It is well known that the semigroup B(S) of all bi-ideal elements of an le-semigroup S is a band if and only if S is both regular and intra-regular. Here we show that B(S) is a band if and only if it is a normal band and ...
