$q$-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.

\(f(q)\) \(=\) \( q + ( 1 + 2 i ) q^{5} + 2 i q^{7} +O(q^{10})\) \( q + ( 1 + 2 i ) q^{5} + 2 i q^{7} -4 q^{11} + 4 i q^{13} -4 q^{19} -2 i q^{23} + ( -3 + 4 i ) q^{25} + 2 q^{29} + ( -4 + 2 i ) q^{35} -4 i q^{37} -2 q^{41} + 6 i q^{43} + 6 i q^{47} + 3 q^{49} + 4 i q^{53} + ( -4 - 8 i ) q^{55} + 12 q^{59} -10 q^{61} + ( -8 + 4 i ) q^{65} + 14 i q^{67} + 8 q^{71} + 8 i q^{73} -8 i q^{77} + 16 q^{79} + 2 i q^{83} + 6 q^{89} -8 q^{91} + ( -4 - 8 i ) q^{95} -16 i q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q + 2q^{5} + O(q^{10}) \) \( 2q + 2q^{5} - 8q^{11} - 8q^{19} - 6q^{25} + 4q^{29} - 8q^{35} - 4q^{41} + 6q^{49} - 8q^{55} + 24q^{59} - 20q^{61} - 16q^{65} + 16q^{71} + 32q^{79} + 12q^{89} - 16q^{91} - 8q^{95} + O(q^{100}) \)
