Signatures of alternating group actions with non-zero quotient genus
Jennifer Paulhus, Aaron Wootton
We classify up to signature all the ways the alternating group can act on a compact Riemann surfaces when the quotient genus is greater than . In particular, we prove that…

Completely decomposable modular Jacobians
Jennifer Paulhus, Andrew V. Sutherland
We use recently developed algorithms and a new database of modular curves constructed for the L-functions and Modular Forms Database to enumerate completely decomposable modular Ja…
