Dimensions
The following table gives the dimensions of various subspaces of \(M_{11}(\Gamma_1(6))\).
| Total | New | Old | |
|---|---|---|---|
| Modular forms | 12 | 4 | 8 |
| Cusp forms | 8 | 4 | 4 |
| Eisenstein series | 4 | 0 | 4 |
Trace form
Decomposition of \(S_{11}^{\mathrm{new}}(\Gamma_1(6))\)
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 |
|---|---|---|---|---|
| 6.11.b | \(\chi_{6}(5, \cdot)\) | 6.11.b.a | 4 | 1 |
Decomposition of \(S_{11}^{\mathrm{old}}(\Gamma_1(6))\) into lower level spaces
\( S_{11}^{\mathrm{old}}(\Gamma_1(6)) \cong \) \(S_{11}^{\mathrm{new}}(\Gamma_1(1))\)\(^{\oplus 4}\)\(\oplus\)\(S_{11}^{\mathrm{new}}(\Gamma_1(2))\)\(^{\oplus 2}\)\(\oplus\)\(S_{11}^{\mathrm{new}}(\Gamma_1(3))\)\(^{\oplus 2}\)\(\oplus\)\(S_{11}^{\mathrm{new}}(\Gamma_1(6))\)\(^{\oplus 1}\)
