Dimensions
The following table gives the dimensions of various subspaces of \(M_{26}(\Gamma_1(6))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 27 | 3 | 24 |
Cusp forms | 23 | 3 | 20 |
Eisenstein series | 4 | 0 | 4 |
Trace form
Decomposition of \(S_{26}^{\mathrm{new}}(\Gamma_1(6))\)
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 the newforms together with their dimension.
Label | \(\chi\) | Newforms | Dimension | \(\chi\) degree |
---|---|---|---|---|
6.26.a | \(\chi_{6}(1, \cdot)\) | 6.26.a.a | 1 | 1 |
6.26.a.b | 1 | |||
6.26.a.c | 1 |
Decomposition of \(S_{26}^{\mathrm{old}}(\Gamma_1(6))\) into lower level spaces
\( S_{26}^{\mathrm{old}}(\Gamma_1(6)) \cong \) \(S_{26}^{\mathrm{new}}(\Gamma_1(1))\)\(^{\oplus 4}\)\(\oplus\)\(S_{26}^{\mathrm{new}}(\Gamma_1(2))\)\(^{\oplus 2}\)\(\oplus\)\(S_{26}^{\mathrm{new}}(\Gamma_1(3))\)\(^{\oplus 2}\)
