$q$-expansion

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.

\(f(q)\) \(=\) \( q + \beta q^{5} + (3 \beta - 1) q^{7} + (\beta - 4) q^{13} + ( - \beta + 4) q^{17} + ( - 3 \beta + 1) q^{19} + (4 \beta - 4) q^{23} + (\beta - 4) q^{25} + (\beta + 7) q^{29} + (3 \beta - 4) q^{31} + (2 \beta + 3) q^{35}+ \cdots - 9 \beta q^{97} +O(q^{100}) \) Copy content Toggle raw display
