Higher a-numbers in -towers via Counting Lattice Points
Jeremy Booher, Jack Hsieh, Rakesh Rivera +3
Booher, Cais, Kramer-Miller and Upton study a class of -tower of curves in characteristic with ramification controlled by an integer . In the special case that…
Doubly isogenous curves of genus two with a rational action of
Jeremy Booher, Everett W. Howe, Andrew V. Sutherland +1
Let and be curves over a finite field , provided with embeddings and $ι'$ into their Jacobian varieties. Let and be the pullbacks (via these e…
Ekedahl-Oort types of -covers in characteristic
Jeremy Booher, Steven R. Groen, Joe Kramer-Miller
In this article we study the Ekedahl-Oort types of -Galois covers in characteristic two. When the base curve is ordinary, we show that the…
Computing Crystalline Cohomology and p-Divisible Groups for Curves over Finite Fields
Jeremy Booher
Let be a smooth projective curve over a finite field of characteristic . We describe and implement a practical algorithm for computing the -divisible group $Jac(X)[p^\inf…
Producing supersingular curves of genus five
Jeremy Booher, Rachel Pries
For a prime congruent to three modulo four, we prove that there exists a smooth curve of genus five in characteristic that is supersingular. We produce this curve as an unr…
Supersingular curves via the Shimura--Taniyama method
Jeremy Booher, Rachel Pries
For a curve which admits an abelian cover of the projective line branched at three points, we study when its reduction to positive characteristic is supersingular. Using the method…
