$q$-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.

\(f(q)\) \(=\) \( q + i q^{3} + ( 2 - i ) q^{5} + i q^{7} + 2 q^{9} +O(q^{10})\) \( q + i q^{3} + ( 2 - i ) q^{5} + i q^{7} + 2 q^{9} - q^{11} -i q^{13} + ( 1 + 2 i ) q^{15} + 3 i q^{17} + 4 q^{19} - q^{21} + 2 i q^{23} + ( 3 - 4 i ) q^{25} + 5 i q^{27} + q^{29} -6 q^{31} -i q^{33} + ( 1 + 2 i ) q^{35} -2 i q^{37} + q^{39} -10 q^{41} + ( 4 - 2 i ) q^{45} -9 i q^{47} - q^{49} -3 q^{51} -14 i q^{53} + ( -2 + i ) q^{55} + 4 i q^{57} -6 q^{59} -4 q^{61} + 2 i q^{63} + ( -1 - 2 i ) q^{65} -10 i q^{67} -2 q^{69} -16 q^{71} + 10 i q^{73} + ( 4 + 3 i ) q^{75} -i q^{77} + 11 q^{79} + q^{81} + 4 i q^{83} + ( 3 + 6 i ) q^{85} + i q^{87} -12 q^{89} + q^{91} -6 i q^{93} + ( 8 - 4 i ) q^{95} + 19 i q^{97} -2 q^{99} +O(q^{100})\)
