Dimensions
The following table gives the dimensions of various subspaces of \(M_{46}(\Gamma_1(2))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 12 | 4 | 8 |
Cusp forms | 10 | 4 | 6 |
Eisenstein series | 2 | 0 | 2 |
Trace form
Decomposition of \(S_{46}^{\mathrm{new}}(\Gamma_1(2))\)
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 |
---|---|---|---|---|
2.46.a | \(\chi_{2}(1, \cdot)\) | 2.46.a.a | 2 | 1 |
2.46.a.b | 2 |
Decomposition of \(S_{46}^{\mathrm{old}}(\Gamma_1(2))\) into lower level spaces
\( S_{46}^{\mathrm{old}}(\Gamma_1(2)) \cong \) \(S_{46}^{\mathrm{new}}(\Gamma_1(1))\)\(^{\oplus 2}\)
