q-Expansions

We can associate a theta series to any pair of elements of a Brandt module, which give embeddings (with respect to any fixed module element) of the Brandt module in a space of weight 2 modular forms.

ThetaSeries(x, y, prec) : ModBrdtElt, ModBrdtElt, RngIntElt -> RngSerElt
Returns the theta series associated to the pair (x, y) of elements of a Brandt module, as an element of a power series ring.
qExpansionBasis(M, prec) : ModBrdt, RngIntElt -> SeqEnum
A sequence of power series elements, to precision prec, spanning the image of the theta functions associated to pairs in the Brandt module M.
