DESCRIPTION:Speaker: Rachel Newton\nhosted by Tim Browning\nAbstract: Let E
  and E′ be elliptic curves over Q with complex multiplication by the rin
 g of integers of an imaginary quadratic field K and let Y = Kum(E×E′) b
 e the minimal desingularisation of the quotient of E×E′ by the action o
 f −1. We study the Brauer groups of such surfaces Y and use them to furn
 ish new examples of transcendental Brauer–Manin obstructions to weak app
 roximation. This is joint work with Mohamed Alaa Tawfik.
