Let $X$ be a topological space and let ${\mathcal{B}}$ be a barrier, with rank denoted by $rk({\mathcal{B}})$. Write $\lfloor rk({\mathcal{B}})\rfloor$ for the greatest integer-or-…

Let $1<p<2$, $K>0$, and $0<q<1/p$, and set … For these parameters, the paper proves that there is a traditional barrier at $(0,0)$ for $\Theta$, although $(0,0)$ is irregular. Sing…
