Bianchi period polynomials: Hecke action and congruences
Lewis Combes
Let be a Bianchi group associated to one of the five Euclidean imaginary quadratic fields. We show that the space of weight period polynomials for is ``dual'' to the…

Computing Selmer groups associated to mod p Galois representations
Lewis Combes
We present methods to compute Selmer groups associated to mod p Galois representations rho over a number field K, with a particular focus on comparing their ranks with periods comi…
