SUMMARY:Model Theory Working Seminar
CLASS:PUBLIC
DESCRIPTION:MOSHE KAMENSKY\, BEN-GURION UNIVERSITY\n\n\"HIGHER INTERNAL COV
 ERS\"\n\nIn model theory\, internality is a relationship between definable
  sets\nthat entails the existence of a definable Galois group\, with defin
 able\nGalois correspondence. It can be formulated as an equivalence betwee
 n\ncertain expansion of a theory T (internal covers) and groupoids\ndefina
 ble in that theory. I will describe a partial generalisation of\nthis corr
 espondence to higher dimensions.\n\nMC 5479
