Newform orbit 582.2.a.h

Trace form

The 2 newforms in this orbit are conjugate over Q\mathbb{Q}; the sum of their qq-expansions is

Coefficient field

The coefficients ana_n generate Q(5)\mathbb{Q}(\sqrt{5}). It is generated by the eigenvalue Ξ±\alpha of T=T5+3T7+5T11+7T13T = T_{5} + 3T_{7} + 5T_{11} + 7T_{13}, whose minimal polynomial is

For pβˆ₯Np \parallel N every form in the orbit has ap=βˆ’pk/2βˆ’1wpa_p = -p^{k/2-1} w_p. The Fricke sign is wN=βˆ’1w_N = -1, so the sign of the functional equation is (βˆ’1)k/2wN=+1(-1)^{k/2} w_N = +1: each L-function in the orbit has even analytic rank.

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.409 s (one thread) and proven: the dimensions are certified, and the characteristic polynomial of TT over Z\mathbb{Z} is reconstructed by CRT past a rigorous coefficient bound. The label, dimension and tr⁑ap\operatorname{tr} a_p for every p<1000p < 1000 equal LMFDB's.
