Canonical Embedding

Canonical embeddings of modular curves


This pari program can be used, in conjunction with the tables of eigenforms, to compute the degree d relations satisfied by cusp forms in S2(Gamma0(N)). The algorithm is described in Steven Galbraith's Oxford Ph.D. thesis. The implimentation (written in one afternoon) is not efficient, but it was good enough for the application of determining all trigonal modular curves, for which it was written.
