Newform orbit 589.2.a.d

Trace form

The 10 newforms in this orbit are conjugate over $\mathbb{Q}$ ; the sum of their $q$ -expansions is

$10q - 7q^{3} + 6q^{4} - 7q^{5} - 5q^{6} - 2q^{7} + q^{9} - 10q^{10} - 22q^{11} - 22q^{12} - q^{13} - 13q^{14} + 6q^{15} + 10q^{16} - 10q^{17} + 12q^{18} - 10q^{19} - 24q^{20} - 2q^{21} + 4q^{22} - 17q^{23} - 8q^{24} + O(q^{25})$

Coefficient field

The coefficients $a_n$ generate a number field of degree 10. It is generated by the eigenvalue $\alpha$ of $T = T_{2} + T_{3}$ , whose minimal polynomial is

$x^{10} + 7x^{9} + x^{8} - 63x^{7} - 48x^{6} + 155x^{5} + 67x^{4} - 103x^{3} - 32x^{2} + 16x + 4$

Atkin–Lehner signs

$p$	$w_p$
19	$+1$
31	$+1$

For $p \parallel N$ every form in the orbit has $a_p = -p^{k/2-1} w_p$ . The Fricke sign is $w_N = +1$ , so the sign of the functional equation is $(-1)^{k/2} w_N = -1$ : each L-function in the orbit has odd analytic rank.

$\operatorname{tr} a_n$ for every $n \le 1000$ is in the JSON.

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.201 s (one thread) and proven: the dimensions are certified, and the characteristic polynomial of $T$ over $\mathbb{Z}$ is reconstructed by CRT past a rigorous coefficient bound. The label, dimension and $\operatorname{tr} a_p$ for every $p < 1000$ equal LMFDB's.

The engine's checks
