DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OLS/183/">Ex
 pansions of ordered Abelian groups by unary predicates</a>\nby John Goodri
 ck (Universidad de los Andes) as part of Online logic seminar\n\n\nAbstrac
 t\nI will talk about some recent results on model-theoretic tameness prope
 rties of expansions of ordered Abelian groups by unary predicates. In part
 icular\, I will discuss properties such as (strongly) NIP\, having finite 
 dp-rank\, and dp-minimality and how these relate to topological and arithm
 etic properties of sets definable in the structure. Furthermore I will pre
 sent some ongoing work on quantifier elimination for expansions of regular
  ordered abelian groups by a predicate for a dense subgroup.\n
