Congruence frames of frames and $κ$ -frames

Graham Manuell

We describe the congruence lattices of frames and $κ$ -frames. We look at the role that congruence biframes play in the category of strictly zero-dimensional biframes and discuss so…

A special class of congruences on $κ$ -frames

Graham Manuell

Madden has shown that in contrast to the situation with frames, the smallest dense quotient of a $κ$ -frame need not be Boolean. We characterise these so-called d-reduced $κ$ -frames…
