Hypergeometric -functions in average polynomial time, II

Edgar Costa, Kiran S. Kedlaya, David Roe

For a fixed positive integer , we describe an algorithm for computing, for all primes , the mod- reduction of the trace of Frobenius at of a fixed hypergeomet…

Hypergeometric L-functions in average polynomial time

Edgar Costa, Kiran S. Kedlaya, David Roe

We describe an algorithm for computing, for all primes , the mod- reduction of the trace of Frobenius at of a fixed hypergeometric motive in time quasilinear in $X…

Counterexamples to a Conjecture of Ahmadi and Shparlinski

Taylor Dupuy, Kiran Kedlaya, David Roe +1

Ahmadi-Shparlinski conjectured that every ordinary, geometrically simple Jacobian over a finite field has maximal angle rank. Using the L-Functions and Modular Forms Database, we p…

Isogeny Classes of Abelian Varieties over Finite Fields in the LMFDB

Taylor Dupuy, Kiran Kedlaya, David Roe +1

This document is intended to summarize the theory and methods behind fq_isog collection inside the ab_var database in the LMFDB as well as some observations gleaned from these data…

ZpL: a p-adic precision package

Xavier Caruso, David Roe, Tristan Vaccon

We present a new package ZpL for the mathematical software system SM. It implements a sharp tracking of precision on p-adic numbers, following the theory of ultrametric precision i…
