Towers of measurable functions


We give mathematical reformulations of the cardinals $\frak p$ and $\frak t$ in terms of families of measurable functions, proving that both of these cardinals are invariant under the addition of one random real. We also describe the cardinal $\frak f$ after adding one random real.
