## $q$-expansion

comment: q-expansion

sage: f.q_expansion() # note that sage often uses an isomorphic number field

gp: mfcoefs(f, 20)

Coefficients of the $$q$$-expansion are expressed in terms of $$i = \sqrt{-1}$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + i q^{7}+O(q^{10})$$ q + i * q^7 $$q + i q^{7} - 4 q^{11} + 3 i q^{13} - i q^{17} + 8 q^{19} + 3 i q^{23} - 2 q^{29} - 4 q^{31} + i q^{37} + 10 q^{41} - i q^{43} - i q^{47} + 3 q^{49} + i q^{53} + 2 q^{61} + 3 i q^{67} - 12 q^{71} - 5 i q^{73} - 4 i q^{77} - 8 q^{79} + 5 i q^{83} - 6 q^{89} - 12 q^{91} + 5 i q^{97} +O(q^{100})$$ q + i * q^7 - 4 * q^11 + 3*i * q^13 - i * q^17 + 8 * q^19 + 3*i * q^23 - 2 * q^29 - 4 * q^31 + i * q^37 + 10 * q^41 - i * q^43 - i * q^47 + 3 * q^49 + i * q^53 + 2 * q^61 + 3*i * q^67 - 12 * q^71 - 5*i * q^73 - 4*i * q^77 - 8 * q^79 + 5*i * q^83 - 6 * q^89 - 12 * q^91 + 5*i * q^97 $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2 q+O(q^{10})$$ 2 * q $$2 q - 8 q^{11} + 16 q^{19} - 4 q^{29} - 8 q^{31} + 20 q^{41} + 6 q^{49} + 4 q^{61} - 24 q^{71} - 16 q^{79} - 12 q^{89} - 24 q^{91}+O(q^{100})$$ 2 * q - 8 * q^11 + 16 * q^19 - 4 * q^29 - 8 * q^31 + 20 * q^41 + 6 * q^49 + 4 * q^61 - 24 * q^71 - 16 * q^79 - 12 * q^89 - 24 * q^91
