Dimensions
The following table gives the dimensions of various subspaces of \(M_{26}(\Gamma_1(3))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 9 | 5 | 4 |
Cusp forms | 7 | 5 | 2 |
Eisenstein series | 2 | 0 | 2 |
Trace form
Decomposition of \(S_{26}^{\mathrm{new}}(\Gamma_1(3))\)
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 |
---|---|---|---|---|
3.26.a | \(\chi_{3}(1, \cdot)\) | 3.26.a.a | 2 | 1 |
3.26.a.b | 3 |
Decomposition of \(S_{26}^{\mathrm{old}}(\Gamma_1(3))\) into lower level spaces
\( S_{26}^{\mathrm{old}}(\Gamma_1(3)) \cong \) \(S_{26}^{\mathrm{new}}(\Gamma_1(1))\)\(^{\oplus 2}\)
