Newform orbit 587.2.a.a

Trace form

The 5 newforms in this orbit are conjugate over $\mathbb{Q}$ ; the sum of their $q$ -expansions is

$5q - 3q^{2} - 2q^{3} + 5q^{4} + 2q^{5} - 4q^{7} - 9q^{8} - 3q^{9} + q^{11} - 12q^{12} - 20q^{13} - 5q^{14} - 12q^{15} - 3q^{16} + 4q^{17} - 4q^{18} + 3q^{19} + 12q^{20} + 9q^{21} + 5q^{22} - 4q^{23} + 29q^{24} + O(q^{25})$

Coefficient field

The coefficients $a_n$ generate a number field of degree 5. It is generated by the eigenvalue $\alpha$ of $T = T_{2} + T_{3}$ , whose minimal polynomial is

$x^{5} + 5x^{4} - x^{3} - 7x^{2} + 2x + 1$

Atkin–Lehner signs

$p$	$w_p$
587	$+1$

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 0.206 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

dim M^+ at levels [1, 587]: [0, 50] (certified at ell = 2147470837)
T = [(2, 1), (3, 1)]; h of degree 49 = 1 x 49 (phi(ord eps) x dim S_k^new); 5 primes, 0 rejected
