Preservation of splitting families and cardinal characteristics of the continuum
Martin Goldstern, Jakob Kellner, Diego A. Mejía +1
We show how to construct, via forcing, splitting families than are preserved by a certain type of finite support iterations. As an application, we construct a model where 15 classi…

Controlling cardinal characteristics without adding reals
Martin Goldstern, Jakob Kellner, Diego A. Mejía +1
We investigate the behavior of cardinal characteristics of the reals under extensions that do not add new -sequences (for some regular ). As an application, we show that c…
