In [14, 15], 2 1 1 T and 2 T spaces have been introduced and investigated. In this paper, their properties are further studied. The 2 1 1T and 2 T separation axioms are described with molecular nets and ideals, some interesting new results are found. We also give applications of some weakly continuous order homophisms in separation axioms.
Keywords:2 1 1 T and 2
