Newform orbit 563.2.a.d

Trace form

The 9 newforms in this orbit are conjugate over Q\mathbb{Q}; the sum of their qq-expansions is

Coefficient field

The coefficients ana_n generate a number field of degree 9. It is generated by the eigenvalue Ξ±\alpha of T=T2+3T3T = T_{2} + 3T_{3}, whose minimal polynomial is

x9+23x8+136x7βˆ’534x6βˆ’8397x5βˆ’26006x4+4518x3+132740x2+151351xβˆ’2503x^{9} + 23x^{8} + 136x^{7} - 534x^{6} - 8397x^{5} - 26006x^{4} + 4518x^{3} + 132740x^{2} + 151351x - 2503

Atkin–Lehner signs

ppwpw_p
563+1+1

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=+1w_N = +1, so the sign of the functional equation is (βˆ’1)k/2wN=βˆ’1(-1)^{k/2} w_N = -1: each L-function in the orbit has odd analytic rank.

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0.299 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.

The engine's checks
  • dim M^+ at levels [1, 563]: [0, 48] (certified at ell = 2147482367)
  • T = [(2, 1), (3, 3)]; h of degree 47 = 1 x 47 (phi(ord eps) x dim S_k^new); 7 primes, 0 rejected
