Dimensions
The following table gives the dimensions of various subspaces of \(M_{4}(\Gamma_1(19))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 54 | 52 | 2 |
Cusp forms | 36 | 36 | 0 |
Eisenstein series | 18 | 16 | 2 |
Trace form
Decomposition of \(S_{4}^{\mathrm{new}}(\Gamma_1(19))\)
We only show spaces with even parity, since no modular forms exist when this condition is not satisfied. Within each space \( S_k^{\mathrm{new}}(N, \chi) \) we list available newforms together with their dimension.
