Conductors of wild extensions of local fields, especially in mixed characteristic (0,2)
Andrew Obus
If K_0 is the fraction field of the Witt vectors over an algebraically closed field k of characteristic p, we calculate upper bounds on the conductor of higher ramification for (th…

On Colmez's product formula for periods of CM-abelian varieties
Andrew Obus
Colmez conjectured a product formula for periods of abelian varieties with complex multiplication by a field K, analogous to the standard product formula in algebraic number theory…

The (local) lifting problem for curves
Andrew Obus
The lifting problem that we consider asks: given a smooth curve in characteristic p and a group of automorphisms, can we lift the curve, along with the automorphisms, to characteri…
