Robust reflection principles
Chris Lambie-Hanson
A cardinal satisfies a property P robustly if, whenever is a forcing poset and , satisfies P in . We study the extent to wh…
Covering properties and square principles
Chris Lambie-Hanson
Covering matrices were introduced by Viale in his proof that the Singular Cardinals Hypothesis follows from the Proper Forcing Axiom. In the course of his work and in subsequent wo…
Squares and narrow systems
Chris Lambie-Hanson
A narrow system is a combinatorial object introduced by Magidor and Shelah in connection with work on the tree property at successors of singular cardinals. In analogy to the tree…
Bounded stationary reflection II
Chris Lambie-Hanson
Bounded stationary reflection at a cardinal is the assertion that every stationary subset of reflects but there is a stationary subset of that does not reflect at arbit…
