$q$-expansion

Copy content gp:mfcoefs(f, 20)
 

Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \frac{1}{2}(1 + \sqrt{5})\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + ( - \beta - 1) q^{2} + 3 \beta q^{4} + (2 \beta + 1) q^{7} + ( - 4 \beta - 1) q^{8} + (2 \beta + 2) q^{11} + 2 \beta q^{13} + ( - 5 \beta - 3) q^{14} + (3 \beta + 5) q^{16} + (4 \beta - 4) q^{17} + (2 \beta - 5) q^{19}+ \cdots + ( - 14 \beta - 6) q^{98}+O(q^{100}) \) Copy content Toggle raw display
