DESCRIPTION:Title: <a href="https://researchseminars.org/talk/POINT/33/">R
 eduction of post-critically finite polynomials</a>\nby Bella Tobin (Oklaho
 ma State University) as part of POINT: New Developments in Number Theory\n
 \n\nAbstract\nPost-critically finite maps are described as dynamical analo
 gs of CM Abelian Varieties. A CM abelian varieties over a number field $K$
  has everywhere good reduction in some finite extension $L/K$. This motiva
 tes us to ask the question: do PCF maps have good reduction? We can use a 
 particular family of maps\, dynamical Belyi  polynomials\, to provide nece
 ssary and sufficient conditions for a PCF polynomial of degree $d$ to have
  potential good reduction at a prime $p$. This is joint work with Jacqueli
 ne Anderson and Michelle Manes.\n
