Dimensions
The following table gives the dimensions of various subspaces of \(M_{2}(\Gamma_1(93))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 380 | 269 | 111 |
Cusp forms | 261 | 209 | 52 |
Eisenstein series | 119 | 60 | 59 |
Trace form
Decomposition of \(S_{2}^{\mathrm{new}}(\Gamma_1(93))\)
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.
Decomposition of \(S_{2}^{\mathrm{old}}(\Gamma_1(93))\) into lower level spaces
\( S_{2}^{\mathrm{old}}(\Gamma_1(93)) \cong \) \(S_{2}^{\mathrm{new}}(\Gamma_1(31))\)\(^{\oplus 2}\)
