 How to take over your† local government using mathematics</a>\nby Ruben 
 Seyer (Chalmers University of Technology & University of Gothenburg) as pa
 rt of Gothenburg PhD seminar\n\nLecture held in MVL14.\n\nAbstract\n† If
  you are elected in Sweden and under some assumptions\n\nIt is a well-know
 n problem that mathematics is easy but politics is difficult.\nElectoral m
 athematics is concerned with constructing algorithms that convert vote cou
 nts to seat counts. Unfortunately\, nobody can agree on what makes such an
  algorithm "fair".\nWe review some famous theorems that show why.\nWe also
  review divisor methods\, in use in most proportional elections. These sat
 isfy certain satisfying theorems which may be indicative of their "fairnes
 s".\nFinally\, we consider some takeover attacks in local councils possibl
 e due to mathematical deficiencies in the Swedish electoral system highlig
 hted by Janson & Linusson (2022).\n
