$q$-expansion

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

\(f(q)\) \(=\) \( q + ( -1 + 2 i ) q^{5} + 4 i q^{7} +O(q^{10})\) \( q + ( -1 + 2 i ) q^{5} + 4 i q^{7} + 4 i q^{13} + 8 q^{19} -4 i q^{23} + ( -3 - 4 i ) q^{25} -6 q^{29} -8 q^{31} + ( -8 - 4 i ) q^{35} + 4 i q^{37} -6 q^{41} + 4 i q^{43} -4 i q^{47} -9 q^{49} + 12 i q^{53} -6 q^{61} + ( -8 - 4 i ) q^{65} -12 i q^{67} + 16 q^{71} + 8 q^{79} + 12 i q^{83} -10 q^{89} -16 q^{91} + ( -8 + 16 i ) q^{95} -8 i q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - 2q^{5} + O(q^{10}) \) \( 2q - 2q^{5} + 16q^{19} - 6q^{25} - 12q^{29} - 16q^{31} - 16q^{35} - 12q^{41} - 18q^{49} - 12q^{61} - 16q^{65} + 32q^{71} + 16q^{79} - 20q^{89} - 32q^{91} - 16q^{95} + O(q^{100}) \)
