Dimensions
The following table gives the dimensions of various subspaces of \(M_{14}(\Gamma_1(5))\).
| Total | New | Old | |
|---|---|---|---|
| Modular forms | 15 | 13 | 2 |
| Cusp forms | 11 | 11 | 0 |
| Eisenstein series | 4 | 2 | 2 |
Trace form
Decomposition of \(S_{14}^{\mathrm{new}}(\Gamma_1(5))\)
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.
| Label | \(\chi\) | Newforms | Dimension | \(\chi\) degree |
|---|---|---|---|---|
| 5.14.a | \(\chi_{5}(1, \cdot)\) | 5.14.a.a | 2 | 1 |
| 5.14.a.b | 3 | |||
| 5.14.b | \(\chi_{5}(4, \cdot)\) | 5.14.b.a | 6 | 1 |
