DESCRIPTION:Speakers: David Harbater (University of Pennsylvania)\n\nThe O
ort conjecture states that every cyclic branched cover of curves in charac
teristic p can be lifted to such a cover in characteristic zero. This rai
ses the more general question of which finite groups G have the property t
hat every G-Galois branched cover of curves in characteristic p can be lif
ted to characteristic zero. While this can be viewed as analogous to the
inverse Galois problem\, the situation here turns out to be very different
\, and the finite groups that have the lifting property are quite constrai
ned. This talk will discuss the Oort conjecture and its generalizations\,
presenting in particular recent developments.\n\nhttps://indico.math.cnrs
