Dimensions
The following table gives the dimensions of various subspaces of \(M_{5}(\Gamma_1(22))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 70 | 20 | 50 |
Cusp forms | 50 | 20 | 30 |
Eisenstein series | 20 | 0 | 20 |
Trace form
Decomposition of \(S_{5}^{\mathrm{new}}(\Gamma_1(22))\)
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 |
---|---|---|---|---|
22.5.b | \(\chi_{22}(21, \cdot)\) | 22.5.b.a | 4 | 1 |
22.5.d | \(\chi_{22}(7, \cdot)\) | 22.5.d.a | 16 | 4 |
Decomposition of \(S_{5}^{\mathrm{old}}(\Gamma_1(22))\) into lower level spaces
\( S_{5}^{\mathrm{old}}(\Gamma_1(22)) \cong \) \(S_{5}^{\mathrm{new}}(\Gamma_1(11))\)\(^{\oplus 2}\)
