Towers of measurable functions

James Hirschorn (2000)

Fundamenta Mathematicae

Similarity:

We formulate variants of the cardinals f, p and t in terms of families of measurable functions, in order to examine the effect upon these cardinals of adding one random real.

Examples for Souslin forcing

Haim Judah, Andrzej Rosłanowski, Saharon Shelah (1994)

Fundamenta Mathematicae

Similarity:

We give several examples of Souslin forcing notions. For instance, we show that there exists a proper analytical forcing notion without ccc and with no perfect set of incompatible elements, we give an example of a Souslin ccc partial order without the Knaster property, and an example of a totally nonhomogeneous Souslin forcing notion.
