"Higher internal covers"

In model theory, internality is a relationship between definable sets that entails the existence of a definable Galois group, with definable Galois correspondence. It can be formulated as an equivalence between certain expansion of a theory T (internal covers) and groupoids definable in that theory. I will describe a partial generalisation of this correspondence to higher dimensions.

"Normal schemes and what-not"

We’ll discuss what makes a scheme “normal”, and in the event that your scheme is weird we’ll see how to “normalize” it. I plan to discuss other related concepts; maybe regularity and local factoriality.
