More separations of cardinal characteristics of the strong measure zero ideal

arXiv:2502.01646

Abstract

Let be the -ideal of the null sets of reals. We introduce a new property of forcing notions that enable control of the additivity of after finite support iterations. This is applied to answer some open questions from the work of Brendle, the first author, and Mejía~\cite{BCM2}.
