$q$-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.

\(f(q)\) \(=\) \( q + i q^{2} - q^{4} + ( -2 - i ) q^{5} + i q^{7} -i q^{8} +O(q^{10})\) \( q + i q^{2} - q^{4} + ( -2 - i ) q^{5} + i q^{7} -i q^{8} + ( 1 - 2 i ) q^{10} -4 i q^{13} - q^{14} + q^{16} -2 i q^{17} + 8 q^{19} + ( 2 + i ) q^{20} -8 i q^{23} + ( 3 + 4 i ) q^{25} + 4 q^{26} -i q^{28} -8 q^{29} + 4 q^{31} + i q^{32} + 2 q^{34} + ( 1 - 2 i ) q^{35} -8 i q^{37} + 8 i q^{38} + ( -1 + 2 i ) q^{40} + 12 q^{41} -8 i q^{43} + 8 q^{46} -4 i q^{47} - q^{49} + ( -4 + 3 i ) q^{50} + 4 i q^{52} + 6 i q^{53} + q^{56} -8 i q^{58} -8 q^{59} -6 q^{61} + 4 i q^{62} - q^{64} + ( -4 + 8 i ) q^{65} + 8 i q^{67} + 2 i q^{68} + ( 2 + i ) q^{70} + 4 i q^{73} + 8 q^{74} -8 q^{76} -8 q^{79} + ( -2 - i ) q^{80} + 12 i q^{82} + ( -2 + 4 i ) q^{85} + 8 q^{86} + 4 q^{89} + 4 q^{91} + 8 i q^{92} + 4 q^{94} + ( -16 - 8 i ) q^{95} -12 i q^{97} -i q^{98} +O(q^{100})\)
