$q$-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.

\(f(q)\) \(=\) \( q + i q^{2} + q^{4} + ( -1 - 2 i ) q^{5} -i q^{7} + 3 i q^{8} +O(q^{10})\) \( q + i q^{2} + q^{4} + ( -1 - 2 i ) q^{5} -i q^{7} + 3 i q^{8} + ( 2 - i ) q^{10} + 6 q^{11} + 2 i q^{13} + q^{14} - q^{16} -4 i q^{17} + 6 q^{19} + ( -1 - 2 i ) q^{20} + 6 i q^{22} + ( -3 + 4 i ) q^{25} -2 q^{26} -i q^{28} -2 q^{29} -10 q^{31} + 5 i q^{32} + 4 q^{34} + ( -2 + i ) q^{35} -4 i q^{37} + 6 i q^{38} + ( 6 - 3 i ) q^{40} -2 q^{41} + 4 i q^{43} + 6 q^{44} - q^{49} + ( -4 - 3 i ) q^{50} + 2 i q^{52} + 6 i q^{53} + ( -6 - 12 i ) q^{55} + 3 q^{56} -2 i q^{58} -8 q^{59} -2 q^{61} -10 i q^{62} -7 q^{64} + ( 4 - 2 i ) q^{65} -16 i q^{67} -4 i q^{68} + ( -1 - 2 i ) q^{70} -10 q^{71} + 6 i q^{73} + 4 q^{74} + 6 q^{76} -6 i q^{77} -4 q^{79} + ( 1 + 2 i ) q^{80} -2 i q^{82} + 8 i q^{83} + ( -8 + 4 i ) q^{85} -4 q^{86} + 18 i q^{88} + 6 q^{89} + 2 q^{91} + ( -6 - 12 i ) q^{95} -2 i q^{97} -i q^{98} +O(q^{100})\)
