$q$-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.

\(f(q)\) \(=\) \( q - q^{3} + ( 2 + i ) q^{5} + 4 i q^{7} + q^{9} +O(q^{10})\) \( q - q^{3} + ( 2 + i ) q^{5} + 4 i q^{7} + q^{9} + 4 q^{13} + ( -2 - i ) q^{15} + 8 i q^{19} -4 i q^{21} + 4 i q^{23} + ( 3 + 4 i ) q^{25} - q^{27} -6 i q^{29} + 8 q^{31} + ( -4 + 8 i ) q^{35} -4 q^{37} -4 q^{39} -6 q^{41} + 4 q^{43} + ( 2 + i ) q^{45} -4 i q^{47} -9 q^{49} + 12 q^{53} -8 i q^{57} + 6 i q^{61} + 4 i q^{63} + ( 8 + 4 i ) q^{65} + 12 q^{67} -4 i q^{69} -16 q^{71} + ( -3 - 4 i ) q^{75} -8 q^{79} + q^{81} + 12 q^{83} + 6 i q^{87} -10 q^{89} + 16 i q^{91} -8 q^{93} + ( -8 + 16 i ) q^{95} -8 i q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - 2q^{3} + 4q^{5} + 2q^{9} + O(q^{10}) \) \( 2q - 2q^{3} + 4q^{5} + 2q^{9} + 8q^{13} - 4q^{15} + 6q^{25} - 2q^{27} + 16q^{31} - 8q^{35} - 8q^{37} - 8q^{39} - 12q^{41} + 8q^{43} + 4q^{45} - 18q^{49} + 24q^{53} + 16q^{65} + 24q^{67} - 32q^{71} - 6q^{75} - 16q^{79} + 2q^{81} + 24q^{83} - 20q^{89} - 16q^{93} - 16q^{95} + O(q^{100}) \)
