$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{6}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q -\zeta_{6} q^{5} + ( -2 + 2 \zeta_{6} ) q^{7} +O(q^{10})\) \( q -\zeta_{6} q^{5} + ( -2 + 2 \zeta_{6} ) q^{7} + ( -1 + \zeta_{6} ) q^{11} -\zeta_{6} q^{13} - q^{17} + 4 q^{19} -\zeta_{6} q^{23} + ( -1 + \zeta_{6} ) q^{25} + ( 5 - 5 \zeta_{6} ) q^{29} -\zeta_{6} q^{31} + 2 q^{35} + 6 q^{37} + ( -7 + 7 \zeta_{6} ) q^{43} + ( -7 + 7 \zeta_{6} ) q^{47} + 3 \zeta_{6} q^{49} -12 q^{53} + q^{55} + 4 \zeta_{6} q^{59} + ( -10 + 10 \zeta_{6} ) q^{61} + ( -1 + \zeta_{6} ) q^{65} + 4 \zeta_{6} q^{67} + 12 q^{71} + 6 q^{73} -2 \zeta_{6} q^{77} + ( -15 + 15 \zeta_{6} ) q^{79} + ( -2 + 2 \zeta_{6} ) q^{83} + \zeta_{6} q^{85} -12 q^{89} + 2 q^{91} -4 \zeta_{6} q^{95} + ( -10 + 10 \zeta_{6} ) q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - q^{5} - 2q^{7} + O(q^{10}) \) \( 2q - q^{5} - 2q^{7} - q^{11} - q^{13} - 2q^{17} + 8q^{19} - q^{23} - q^{25} + 5q^{29} - q^{31} + 4q^{35} + 12q^{37} - 7q^{43} - 7q^{47} + 3q^{49} - 24q^{53} + 2q^{55} + 4q^{59} - 10q^{61} - q^{65} + 4q^{67} + 24q^{71} + 12q^{73} - 2q^{77} - 15q^{79} - 2q^{83} + q^{85} - 24q^{89} + 4q^{91} - 4q^{95} - 10q^{97} + O(q^{100}) \)
