$q$-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.

\(f(q)\) \(=\) \( q + ( 1 + i ) q^{3} + ( 3 - 3 i ) q^{7} -i q^{9} +O(q^{10})\) \( q + ( 1 + i ) q^{3} + ( 3 - 3 i ) q^{7} -i q^{9} + 6 q^{21} + ( -1 - i ) q^{23} + ( 4 - 4 i ) q^{27} -6 i q^{29} + 12 q^{41} + ( -9 - 9 i ) q^{43} + ( -7 + 7 i ) q^{47} -11 i q^{49} + 8 q^{61} + ( -3 - 3 i ) q^{63} + ( -3 + 3 i ) q^{67} -2 i q^{69} + 5 q^{81} + ( 11 + 11 i ) q^{83} + ( 6 - 6 i ) q^{87} + 6 i q^{89} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q + 2q^{3} + 6q^{7} + O(q^{10}) \) \( 2q + 2q^{3} + 6q^{7} + 12q^{21} - 2q^{23} + 8q^{27} + 24q^{41} - 18q^{43} - 14q^{47} + 16q^{61} - 6q^{63} - 6q^{67} + 10q^{81} + 22q^{83} + 12q^{87} + O(q^{100}) \)
