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…

Universal Functions
Paul B. Larson, Arnold W. Miller, Juris Steprans +1
A function of two variables F(x,y)is universal iff for every other function G(x,y) there exists functions h(x) and k(y) with G(x,y) = F(h(x),k(y)) Sierpinski showed that assuming t…

Splitting families and complete separability
Heike Mildenberger, Dilip Raghavan, Juris Steprāns
We answer a question from Raghavan and Stepr{ā}ns' paper on weakly tight families by showing that . Then we use this to construct a completely…
