DESCRIPTION:Speaker: Otto Overkamp\nhosted by Tim Browning\nAbstract: We ex
 plain Totaro's notion of pseudo-Abelian varieties and show that they admit
  Néron models over excellent discrete valuation rings. As a next step\, w
 e study those Néron models and generalize the notions of good reduction a
 nd semiabelian reduction to such algebraic groups. We prove that the well-
 known representation-theoretic criteria for good and semiabelian reduction
  due to Néron-Ogg Shafarevich and Grothendieck carry over to the pseudo-A
 belian case\, and give examples to show that our results are the best poss
 ible in most cases.
