Revisiting $b$ and $d$ through Interval Structures

Miguel A. Cardona, Adam Marton

We investigate a family of relational systems arising from interval partitions of $I ¨ $ , inspired by VojtÃ¡Å¡'s characterization of the bounding and dominating numbers. By varying t…

Constant prediction and evasion number, I: Generalization and variants

Miguel A. Cardona, Miroslav RepickÃ½

Using the concept of constant evasion to different sorts of suitable binary relations, we establish many cardinal invariants derived from the established cardinal invariants $\math…

Adding the constant evasion and constant prediction numbers to CichoÅ's maximum

Miguel A. Cardona, Miroslav RepickÃ½, Saharon Shelah

Let $e_{2}^{const}$ be the constant evasion number, that is, the size of the least family $F \subseteq^{I ¨} 2$ of reals such that for each predictor $Ï\colon {}^{<Ï…
