Dimensions
The following table gives the dimensions of various subspaces of \(M_{33}(\Gamma_1(25))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 814 | 746 | 68 |
Cusp forms | 786 | 726 | 60 |
Eisenstein series | 28 | 20 | 8 |
Trace form
Decomposition of \(S_{33}^{\mathrm{new}}(\Gamma_1(25))\)
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 |
---|---|---|---|---|
25.33.c | \(\chi_{25}(7, \cdot)\) | 25.33.c.a | 20 | 2 |
25.33.c.b | 30 | |||
25.33.c.c | 44 | |||
25.33.f | \(\chi_{25}(2, \cdot)\) | n/a | 632 | 8 |
"n/a" means that newforms for that character have not been added to the database yet
Decomposition of \(S_{33}^{\mathrm{old}}(\Gamma_1(25))\) into lower level spaces
\( S_{33}^{\mathrm{old}}(\Gamma_1(25)) \cong \) \(S_{33}^{\mathrm{new}}(\Gamma_1(5))\)\(^{\oplus 2}\)
