We prove the consistency of the existence of a $Q$-set whose square is not a $\Delta$-set and that if there is a $\Delta$-set, then there exists a $\Delta$-set whose all finite powers are $\Delta$-sets.

The property of countable metacompactness of a topological space gets its importance from Dowker's 1951 theorem that the product of a normal space X with the unit interval is again normal iff X is countably metacompact. In a recent paper, Leiderman a

O problema de Scarborough-Stone consiste em perguntar se o produto de espaços topológicos sequencialmente compactos precisa ser enumeravelmente compacto. Nesse trabalho estudamos alguns resultados que surgiram tentando resolver tal problema. Começ

In a paper from 1987, Komjath and Weiss proved that for every regular topological space $X$ of character less than $\mathfrak b$, if $X\rightarrow(top~\omega+1)^1_\omega$, then $X\rightarrow(top~\alpha)^1_\omega$ for all $\alpha<\omega_1$. In additio

Esse trabalho visa comparar o desempenho de diversos países no exame do PISA, em especial Brasil e Japão. Além da comparação de dados estatísticos, será realizada uma análise curricular desses dois países, na tentativa de perceber a influên
We give a new proof of the following theorem due to W. Weiss and P. Komjath: if $X$ is a regular topological space, with character $ < \mathfrak{b}$ and $X \rightarrow (top \omega + 1)^{1}_{\omega}$, then, for all $\alpha < \omega_1$, $X \rightarrow
