$q$-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 \(1,\beta_1,\beta_2,\beta_3,\beta_4\) 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
\( x^{5} - 2x^{4} - 7x^{3} + 4x^{2} + 4x - 2 \)
:
| \(\beta_{1}\) | \(=\) |
\( \nu^{4} - 2\nu^{3} - 7\nu^{2} + 4\nu + 3 \)
|
| \(\beta_{2}\) | \(=\) |
\( 2\nu^{4} - 3\nu^{3} - 15\nu^{2} + 6 \)
|
| \(\beta_{3}\) | \(=\) |
\( -2\nu^{4} + 3\nu^{3} + 15\nu^{2} + 2\nu - 6 \)
|
| \(\beta_{4}\) | \(=\) |
\( 2\nu^{4} - 2\nu^{3} - 18\nu^{2} - 4\nu + 10 \)
|
| \(\nu\) | \(=\) |
\( ( \beta_{3} + \beta_{2} ) / 2 \)
|
| \(\nu^{2}\) | \(=\) |
\( ( -\beta_{4} + 2\beta_{3} + 4\beta_{2} - 2\beta _1 + 4 ) / 2 \)
|
| \(\nu^{3}\) | \(=\) |
\( ( -\beta_{4} + 10\beta_{3} + 14\beta_{2} - 6\beta _1 + 4 ) / 2 \)
|
| \(\nu^{4}\) | \(=\) |
\( ( -9\beta_{4} + 30\beta_{3} + 52\beta_{2} - 24\beta _1 + 30 ) / 2 \)
