[6] is extended to second order fuzzy topological spaces in two different ways. It is shown that these two concepts are hereditary and productive. The relations between first order and second order A A A concepts are studied. The behavior of these concepts with regard to i(6), i^CS), i‘(6), 02(1), (co2(t))^ and co2''(t) are also analysed.
