Osvaldo Guzmán: Properties of MAD families

October 21, 2015, salón Graciela Salicrup, IMATE, UNAM, Mexico City

 

Miguel Angel Mota Gaytán: Baumgartner’s Conjecture and Bounded Forcing Axioms (Part II)

Miguel Angel Mota Gaytán: Baumgartner’s Conjecture and Bounded Forcing Axioms (Part I)

Abstract: Using some variants of weak club guessing we separate some fragments of the proper forcing axiom: we show that for every two indecomposable ordinals α<β, the forcing axiom for the class of all the β-proper posets does not imply the bounded forcing axiom for the class of all the α-proper posets.

Miguel Angel Mota Gaytán: Baumgartner’s Conjecture and Bounded Forcing Axioms (Part I)

Abstract: Using some variants of weak club guessing we separate some fragments of the proper forcing axiom: we show that for every two indecomposable ordinals $\alpha < \beta$, the forcing axiom for the class of all the $\beta$-proper posets does not imply the bounded forcing axiom for the class of all the $\alpha$-proper posets.
