$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \sqrt{2}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + q^{2} + q^{3} + q^{4} + q^{5} + q^{6} + (\beta - 2) q^{7} + q^{8} + q^{9} + q^{10} - 2 q^{11} + q^{12} - q^{13} + (\beta - 2) q^{14} + q^{15} + q^{16} + ( - 2 \beta - 4) q^{17} + q^{18}+ \cdots - 2 q^{99}+O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q + 2 q^{2} + 2 q^{3} + 2 q^{4} + 2 q^{5} + 2 q^{6} - 4 q^{7} + 2 q^{8} + 2 q^{9} + 2 q^{10} - 4 q^{11} + 2 q^{12} - 2 q^{13} - 4 q^{14} + 2 q^{15} + 2 q^{16} - 8 q^{17} + 2 q^{18} + 2 q^{19} + 2 q^{20}+ \cdots - 4 q^{99}+O(q^{100}) \) Copy content Toggle raw display
