Borel Tukey morphisms and combinatorial cardinal invariants of the continuum
Samuel Coskey, Tamás Mátrai, Juris Steprāns
We discuss the Borel Tukey ordering on cardinal invariants of the continuum. We observe that this ordering makes sense for a larger class of cardinals than has previously been cons…

On -like equivalence relations
Tamás Mátrai
For $f \colon [0,1] \rar \real^{+}$, consider the relation on defined by $(x_{n}) \mathbf{E}_{f} (y_{n}) \Leftrightarrow \sum_{n < ω} f(|y_{n} - x_{n}|)…

On splitting infinite-fold covers
Márton Elekes, Tamás Mátrai, Lajos Soukup
Let be a set, $\ka$ be a cardinal number and let $\iH$ be a family of subsets of which covers each at least $\ka$ times. What assumptions can ensure that $\iH$ can…
