About article:
A partial order on a family of continuous functions from a topological space $X$ into $[ω]ω$ is defined as follows
$$ f subseteq* g iff f(x) subseteq*g (x) for any xin X. $$
For this order variants of cardinals ${frak p}$, ${frak t}$ and ${frak h}$ are defined and their values are estimated.
