The biquotient, countably biquotient, hereditarily quotient, and quotient images of q q -spaces are classified. Also, the quotient images of paracompact M M -spaces, and the quotient images of M M -spaces are classified without any separation axioms. New definitions are given for certain familiar classes of spaces to give the definitions more uniformity.
Sequential spaces, Special maps on topological spaces (open, closed, perfect, etc.), Fairly general properties of topological spaces, \(k\)-spaces, Quotient spaces, decompositions in general topology
