Recall that a $P$ -set is a closed set $X$ such that the intersection of countably many neighborhoods of $X$ is again a neighborhood of $X$ . We show that if $\mathfrak{t} = \mathfra…

We prove that, for every n, the topological space ω_n^ω (where ω_n has the discrete topology) can be partitioned into ω_n copies of the Baire space. Using this fact, the authors th…
