The measure algebra adding -many random reals is -FAM-linked

DA Mejía, AF Uribe-Zapata - arXiv preprint arXiv:2312.13443, 2023 - arxiv.org
The notion of $\theta $-FAM-linkedness, introduced in the second author's master thesis, is a
formalization of the notion of strong FAM limits for intervals, whose initial form and …

Cicho\'n's maximum with cardinals of the closed null ideal

T Yamazoe - arXiv preprint arXiv:2412.09069, 2024 - arxiv.org
Let $\mathcal {E} $ denote the $\sigma $-ideal generated by closed null sets on $\mathbb
{R} $. We show that the uniformity and the covering of $\mathcal {E} $ can be added to …

Probability Trees

DA Mejía, AF Uribe-Zapata - arXiv preprint arXiv:2501.07023, 2025 - arxiv.org
In this article, we introduce a formal definition of the concept of probability tree and conduct a
detailed and comprehensive study of its fundamental structural properties. In particular, we …

Anatomy of

DA Mejía - arXiv preprint arXiv:2402.04706, 2024 - arxiv.org
We present a detailed general framework to describe the forcing $\tilde {\mathbb {E}} $,
defined by Kellner, Shelah and Tan\u {a} sie to prove the consistency with ZFC of an …
