Moduli Spaces of Hyperplanar Admissible Flags in Projective Space
George Cooper
We prove the existence of quasi-projective coarse moduli spaces parametrising certain complete flags of subschemes of a fixed projective space up to projective auto…

GIT Constructions of Compactified Universal Jacobians over Stacks of Stable Maps
George Cooper
We prove that any compactified universal Jacobian over any stack of stable maps, defined using torsion-free sheaves which are Gieseker semistable with respect to a relatively ample…

Twisting moduli for GL(2)
Benjamin Bedert, George Cooper, Thomas Oliver +1
We prove various converse theorems for automorphic forms on Γ_0(N), each assuming fewer twisted functional equations than the last. We show that no twisting at all is needed for ho…
