The poor man's tree property
Abstract: Motivated by producing a model where no regular cardinal greater than $\aleph_1$ carries a special Aronszajn tree, we prove that from large cardinals it is consistent that $\aleph_{\omega^2}$ is strong limit and there are no special Aronszajn trees on any regular cardinal in the interval $[\aleph_2,\aleph_{\omega^2+3}]$.
