Titel  Partial orders and topological spaces 
Sammanfattning  I shall talk about topological spaces where arbitrary intersections of open sets are open. It turns out to be equivalent to talk about (partially) preordered sets, so I cannot avoid to talk about such sets as well. I mean to discuss some basic topological notions and their order theoretic interpretation. I shall also try to say something about the relevance of these concepts in digital geometry.
