Groupwise dense number after Miller-type tree forcing
Ryoichi Sato (Kobe University, Japón)
Blass showed that Miller tree forcing increases the groupwise dense number, which is one of the cardinal characteristics in Blass diagram. Miller tree forcing can be extended to Miller-type tree forcing modulo meager ideals on natural numbers. We demonstrate how topological properties can be used to control the properties of infinite combinatorics via the proposed method.
