$q$-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.

\(f(q)\) \(=\) \( q -i q^{2} + i q^{3} - q^{4} + q^{6} + 4 i q^{7} + i q^{8} - q^{9} +O(q^{10})\) \( q -i q^{2} + i q^{3} - q^{4} + q^{6} + 4 i q^{7} + i q^{8} - q^{9} + 4 q^{11} -i q^{12} + 4 q^{14} + q^{16} -2 i q^{17} + i q^{18} - q^{19} -4 q^{21} -4 i q^{22} + 2 i q^{23} - q^{24} -i q^{27} -4 i q^{28} + 6 q^{29} + 6 q^{31} -i q^{32} + 4 i q^{33} -2 q^{34} + q^{36} -8 i q^{37} + i q^{38} + 10 q^{41} + 4 i q^{42} + 12 i q^{43} -4 q^{44} + 2 q^{46} + 10 i q^{47} + i q^{48} -9 q^{49} + 2 q^{51} -2 i q^{53} - q^{54} -4 q^{56} -i q^{57} -6 i q^{58} -4 q^{59} -10 q^{61} -6 i q^{62} -4 i q^{63} - q^{64} + 4 q^{66} + 2 i q^{68} -2 q^{69} -16 q^{71} -i q^{72} + 2 i q^{73} -8 q^{74} + q^{76} + 16 i q^{77} -10 q^{79} + q^{81} -10 i q^{82} + 16 i q^{83} + 4 q^{84} + 12 q^{86} + 6 i q^{87} + 4 i q^{88} + 2 q^{89} -2 i q^{92} + 6 i q^{93} + 10 q^{94} + q^{96} -10 i q^{97} + 9 i q^{98} -4 q^{99} +O(q^{100})\)
