$q$-expansion
comment: q-expansion
sage: f.q_expansion() # note that sage often uses an isomorphic number field
gp: mfcoefs(f, 20)
Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\beta_2,\beta_3\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.
Basis of coefficient ring in terms of a root \(\nu\) of
\( x^{4} - 2x^{3} - 107x^{2} + 108x + 2724 \)
:
| \(\beta_{1}\) | \(=\) |
\( 3\nu - 1 \)
|
| \(\beta_{2}\) | \(=\) |
\( ( \nu^{3} - 2\nu^{2} - 53\nu + 54 ) / 8 \)
|
| \(\beta_{3}\) | \(=\) |
\( ( 3\nu^{2} - 3\nu - 162 ) / 8 \)
|
| \(\nu\) | \(=\) |
\( ( \beta _1 + 1 ) / 3 \)
|
| \(\nu^{2}\) | \(=\) |
\( ( 8\beta_{3} + \beta _1 + 163 ) / 3 \)
|
| \(\nu^{3}\) | \(=\) |
\( ( 16\beta_{3} + 24\beta_{2} + 55\beta _1 + 217 ) / 3 \)
