Dimensions
The following table gives the dimensions of various subspaces of \(M_{19}(\Gamma_1(23))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 407 | 407 | 0 |
Cusp forms | 385 | 385 | 0 |
Eisenstein series | 22 | 22 | 0 |
Trace form
Decomposition of \(S_{19}^{\mathrm{new}}(\Gamma_1(23))\)
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 |
---|---|---|---|---|
23.19.b | \(\chi_{23}(22, \cdot)\) | 23.19.b.a | 1 | 1 |
23.19.b.b | 2 | |||
23.19.b.c | 32 | |||
23.19.d | \(\chi_{23}(5, \cdot)\) | 23.19.d.a | 350 | 10 |
