When is double negation Scott continuous?

Guram Bezhanishvili, Sebastian D. Melzer

Let $L$ be the frame of opens of a $T_{0}$ -space $X$ . We prove that if $X$ is sober and $T_{1}$ , then the double negation nucleus on $L$ is Scott continuous iff $X$ is discrete. It fol…

Maximal d-spectra and locally compact Hausdorff spaces

G. Bezhanishvili, P. Bhattacharjee, S. D. Melzer +1

It is an interesting open problem whether every compact Hausdorff space can be realized as the maximal $d$ -spectrum of an arithmetic frame. We approach this problem by generalizing…

A choice-free approach to Wallman compactifications

Sebastian D Melzer, Cerene Rathilal, Ranjitha Raviprakash

The classical Wallman compactification of a $T_{1}$ -space and the Stone--Čech compactification of a completely regular space rely on choice principles. We show that, by representing…
