    Consistency Strength of Higher Chang’s Conjecture, Without CH.Sean D. Cox - 2011 - Archive for Mathematical Logic 50 (7-8):759-775.
    We prove that ${(\omega_3, \omega_2) \twoheadrightarrow (\omega_2, \omega_1)}$ implies there is an inner model with a weak repeat measure.

    Forcing Axioms, Approachability, and Stationary Set Reflection.Sean D. Cox - 2021 - Journal of Symbolic Logic 86 (2):499-530.
    We prove a variety of theorems about stationary set reflection and concepts related to internal approachability. We prove that an implication of Fuchino–Usuba relating stationary reflection to a version of Strong Chang’s Conjecture cannot be reversed; strengthen and simplify some results of Krueger about forcing axioms and approachability; and prove that some other related results of Krueger are sharp. We also adapt some ideas of Woodin to simplify and unify many arguments in the literature involving preservation of forcing axioms.
