Larson, Paul; Tall, Franklin D.
On the Hereditary Paracompactness of Locally Compact, Hereditarily Normal Spaces
We establish that if it is consistent that there is a supercompact cardinal, then it is consistent that every locally compact, hereditarily normal space which does not include a perfect pre-image of $\omega_1$ is hereditarily paracompact.

Keywords:locally compact, hereditarily normal, paracompact, Axiom R, PFA$^{++}$

2. CMB 2010 (vol 54 pp. 270)

Dow, Alan
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.

Keywords:sequential order, scattered spaces, PFA
