SUMMARY:Valentijn Karemaker (University of Pennsylvania): Arboreal Galois r
 epresentations
DESCRIPTION:Valentijn Karemaker: Arboreal Galois representations are useful
  to describe the Galois theory of iterates of rational maps over number fi
 elds. These representations were introduced in the 1980s to study the prim
 e divisors of non-linear recurrences (also called dynamical sequences).\nW
 e study so-called dynamical Belyi maps\; for these rational maps\, we full
 y determine their arboreal Galois representations\, and prove a result abo
 ut the density of prime divisors of the corresponding dynamical sequences.
 \nThis is joint work with Irene Bouw and Özlem Ejder.
