Dimensions
The following table gives the dimensions of various subspaces of \(M_{7}(\Gamma_1(19))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 99 | 99 | 0 |
Cusp forms | 81 | 81 | 0 |
Eisenstein series | 18 | 18 | 0 |
Trace form
Decomposition of \(S_{7}^{\mathrm{new}}(\Gamma_1(19))\)
We only show spaces with odd 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.
Label | \(\chi\) | Newforms | Dimension | \(\chi\) degree |

19.7.b | \(\chi_{19}(18, \cdot)\) | 19.7.b.a | 1 | 1 |
19.7.b.b | 8 | |||
19.7.d | \(\chi_{19}(8, \cdot)\) | 19.7.d.a | 18 | 2 |
19.7.f | \(\chi_{19}(2, \cdot)\) | 19.7.f.a | 54 | 6 |
