Dimensions
The following table gives the dimensions of various subspaces of \(M_{2}(\Gamma_1(2012))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 127759 | 74296 | 53463 |
Cusp forms | 125250 | 73292 | 51958 |
Eisenstein series | 2509 | 1004 | 1505 |
Trace form
Decomposition of \(S_{2}^{\mathrm{new}}(\Gamma_1(2012))\)
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 |
---|---|---|---|---|
2012.2.a | \(\chi_{2012}(1, \cdot)\) | 2012.2.a.a | 21 | 1 |
2012.2.a.b | 21 | |||
2012.2.b | \(\chi_{2012}(2011, \cdot)\) | n/a | 250 | 1 |
2012.2.e | \(\chi_{2012}(9, \cdot)\) | n/a | 10500 | 250 |
2012.2.h | \(\chi_{2012}(15, \cdot)\) | n/a | 62500 | 250 |
"n/a" means that newforms for that character have not been added to the database yet
Decomposition of \(S_{2}^{\mathrm{old}}(\Gamma_1(2012))\) into lower level spaces
