modular eigenforms with integral coefficients [Maeda's Conjecture]

"He said (and I never understood this comment so feel free to fill me in) that S_k(1;Q) being irreducible as a Hecke module was related to (equivalent to?) a certain L-value not vanishing, and L-value …

Basis for modular forms of half-integral weight

"MAGMA does not seem to include this functionality, either." Basis(HalfIntegralWeightForms(DirichletGroup(4).1^2,11/2)); [ 1 - 88*q^3 - 330*q^4 - 4224*q^7 - 7524*q^8 - 30600*q^11 + O(q^12), …

weight 4 eigenforms with rational coefficients---is it reasonable to expect they all come fr...

"At the level of L-functions, this should force the L-fn attached to the weight two form of g to vanish to order the order of vanishing of the L-fn of the weight 4 form f. How could two modular forms …

Does anyone want a pretty Maass form?

Here it is from Dokchitser in Magma: > L:=LSeries(HilbertClassField(QuadraticField(145)) : Method:="Artin"); > L`prod; [ <L-series of Riemann zeta function, 1>, <L-series of Artin representation …
