Creation

In the current implementation only cusp forms are supported.

BianchiCuspForms(F, N): FldNum, RngOrdIdl -> ModFrmBianchi

VorData: Rec                    Default: 

This creates the cuspidal subspace of the space of Bianchi modular forms over the field \(F\) (an imaginary quadratic field) on \(\Gamma_0(N)\) with weight \(2\). The level \(N\) should be an ideal in the maximal order of \(F\).

The optional argument VorData may be set equal to VoronoiData(M) where M is a previously computed space of forms over the same field. This avoids repeating the time-consuming precomputations that depend only on the field.
