Title: Double EPW-sextics with actions of A7 and irrational GM threefolds

Abstract: We construct two examples of projective hyper-Kähler fourfolds 
of K3[2]-type with an action of the alternating group A7, making them 
some of the most symmetric hyper-Kähler fourfolds. They are realized as 
so called double EPW sextics and this allows us to construct an explicit 
family of irrational Gushel-Mukai threefolds.

All are welcome to attend
