$q$-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.

\(f(q)\) \(=\) \( q + q^{2} - q^{3} + q^{4} - q^{6} + ( - \beta - 3) q^{7} + q^{8} + q^{9} + (3 \beta - 4) q^{11} - q^{12} + ( - \beta - 4) q^{13} + ( - \beta - 3) q^{14} + q^{16} + (6 \beta - 4) q^{17} + q^{18}+ \cdots + (3 \beta - 4) q^{99}+O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q + 2 q^{2} - 2 q^{3} + 2 q^{4} - 2 q^{6} - 7 q^{7} + 2 q^{8} + 2 q^{9} - 5 q^{11} - 2 q^{12} - 9 q^{13} - 7 q^{14} + 2 q^{16} - 2 q^{17} + 2 q^{18} - 3 q^{19} + 7 q^{21} - 5 q^{22} - 5 q^{23} - 2 q^{24}+ \cdots - 5 q^{99}+O(q^{100}) \) Copy content Toggle raw display
