$q$-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.

\(f(q)\) \(=\) \( q + 2 \beta q^{5} -3 \beta q^{7} +O(q^{10})\) \( q + 2 \beta q^{5} -3 \beta q^{7} + 4 q^{11} -3 \beta q^{13} -6 q^{17} -2 q^{19} + 2 \beta q^{23} + 3 q^{25} -4 \beta q^{29} + 3 \beta q^{31} -12 q^{35} -3 \beta q^{37} + 10 q^{41} + 6 q^{43} -2 \beta q^{47} + 11 q^{49} -4 \beta q^{53} + 8 \beta q^{55} + 3 \beta q^{61} -12 q^{65} -4 q^{67} + 2 \beta q^{71} + 16 q^{73} -12 \beta q^{77} + 3 \beta q^{79} + 16 q^{83} -12 \beta q^{85} -14 q^{89} + 18 q^{91} -4 \beta q^{95} -4 q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q + O(q^{10}) \) \( 2q + 8q^{11} - 12q^{17} - 4q^{19} + 6q^{25} - 24q^{35} + 20q^{41} + 12q^{43} + 22q^{49} - 24q^{65} - 8q^{67} + 32q^{73} + 32q^{83} - 28q^{89} + 36q^{91} - 8q^{97} + O(q^{100}) \)
