$q$-expansion

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

\(f(q)\) \(=\) \( q + \beta q^{5} -2 \beta q^{7} +O(q^{10})\) \( q + \beta q^{5} -2 \beta q^{7} -4 q^{11} + 2 q^{13} -\beta q^{17} + 4 \beta q^{19} -4 q^{23} + 3 q^{25} + 5 \beta q^{29} + 6 \beta q^{31} + 4 q^{35} + 8 q^{37} -3 \beta q^{41} -8 \beta q^{43} + 12 q^{47} - q^{49} + 9 \beta q^{53} -4 \beta q^{55} + 8 q^{61} + 2 \beta q^{65} + 4 \beta q^{67} -4 q^{71} -8 q^{73} + 8 \beta q^{77} + 2 \beta q^{79} + 12 q^{83} + 2 q^{85} + 11 \beta q^{89} -4 \beta q^{91} -8 q^{95} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q + O(q^{10}) \) \( 2q - 8q^{11} + 4q^{13} - 8q^{23} + 6q^{25} + 8q^{35} + 16q^{37} + 24q^{47} - 2q^{49} + 16q^{61} - 8q^{71} - 16q^{73} + 24q^{83} + 4q^{85} - 16q^{95} + O(q^{100}) \)
