DESCRIPTION:Speakers: Oana Padurariu (MPIM)\n\nPLeaSANT\nFor the Shimura c
 urves $X_0^D(N)$ the primes of bad reduction are those dividing DN. One wo
 uld expect that the quotients by Atkin—Lehner involutions would inherit 
 these primes of bad reduction\, but this is not always the case. In this t
 alk\, I explain how we classify the unexpected primes of good reduction of
  Atkin–Lehner quotients of modular and Shimura curves of squarefree leve
 ls. This is joint work with Sun Woo Park and John Voight.\n\nhttps://math-
