### Full reflection of stationary sets below $\aleph_ \omega$

by Jech and Shelah. [JeSh:387]

J Symbolic Logic, 1990

It is consistent that for every n >= 2, every
stationary subset of omega_n consisting of ordinals of
cofinality omega_k where k = 0 or k <= n-3 reflects
fully in the set of ordinals of cofinality omega_{n-1} . We
also show that this result is best possible.
