Description: |
Alexander's Subbase Lemma (due to James Waddell Alexander II) is a classical result of topology stating that a topological space X is compact provided that X is compact with respect to a subbasis, that is, every subbasic cover of X has a finite subcover. In this talk we will give a very simple convergence-theoretic argument which, under some conditions, applies not only to compactness but also to core-compactness. We take this as a starting point to a study of the Vietoris construction of dualisable spaces, and of exponentiable spaces.
