rho on an inverse semigroup, there exist the greatest and least congruences rhoT and rhot [resp. rhoK and rhok] respectively in the trace class [resp. the kernel class] of rho. So we have four operators Tau= {T,t,K,k} on the congruence lattice C (S). In this paper, we determine the semigroups generated by the operators Tau, the so called TK-operator semigroups, for bisimple omega-semigroups. We prove that there are exactly four distinct semigroups of Tau-operators up to isomorphism of bisimple omega-semigroups.
