Productively Lindelöf Spaces May All Be $D$ We give easy proofs that (a) the Continuum Hypothesis implies that if
the product of $X$ with every Lindelöf space is Lindelöf, then $X$ is
a $D$-space, and (b) Borel's Conjecture implies every Rothberger space
is Hurewicz.

Sequential Order Under PFA It is shown that it follows from PFA
that there is no
compact scattered space of height greater than $\omega$
in which the sequential order and the scattering heights coincide.

Intuitionistic Fuzzy $\gamma$-Continuity This paper introduces the concepts of
fuzzy $\gamma$-open sets and fuzzy $\gamma$-continuity
in intuitionistic fuzzy topological spaces. After defining the fundamental
concepts of intuitionistic fuzzy sets and intuitionistic fuzzy topological
spaces, we present intuitionistic fuzzy $\gamma$-open sets and
intuitionistic fuzzy $\gamma$-continuity and other results related
topological concepts.
