SUMMARY:Tame expansions of the group of integers - Gabe Conant (DPMMS)
DTSTART:20191126T120000Z

CONTACT:Benedikt Loewe
DESCRIPTION:A common theme in model theory is to fix a mathematical struct
 ure exhibiting some notion of tameness for definable sets\, and study expa
 nsions of that structure by new definable sets which preserve this tamenes
 s. Examples include the study of stable expansions of the complex field an
 d o-minimal expansions of the real field\, both of which have led to spect
 acular applications of model theory to other areas of mathematics. In this
  talk\, I will discuss several results on classifying tame expansions of t
 he group of integers (and other "weakly minimal" groups).
