Dimensions
The following table gives the dimensions of various subspaces of \(M_{2}(\Gamma_1(8978))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 2524929 | 839070 | 1685859 |
Cusp forms | 2511730 | 839070 | 1672660 |
Eisenstein series | 13199 | 0 | 13199 |
Decomposition of \(S_{2}^{\mathrm{new}}(\Gamma_1(8978))\)
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.
