$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \frac{1}{2}(1 + \sqrt{17})\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q - q^{2} - \beta q^{3} + q^{4} + q^{5} + \beta q^{6} - \beta q^{7} - q^{8} + (\beta + 1) q^{9} - q^{10} + 4 q^{11} - \beta q^{12} + (3 \beta - 2) q^{13} + \beta q^{14} - \beta q^{15} + q^{16} + ( - \beta + 6) q^{17} + \cdots + (4 \beta + 4) q^{99} +O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q - 2 q^{2} - q^{3} + 2 q^{4} + 2 q^{5} + q^{6} - q^{7} - 2 q^{8} + 3 q^{9} - 2 q^{10} + 8 q^{11} - q^{12} - q^{13} + q^{14} - q^{15} + 2 q^{16} + 11 q^{17} - 3 q^{18} - 2 q^{19} + 2 q^{20} + 9 q^{21}+ \cdots + 12 q^{99}+O(q^{100}) \) Copy content Toggle raw display
