Singular values of multiple eta-quotients for ramified primes
We determine the conditions under which singular values of multiple η-quotients of square-free level, not necessarily prime to 6, yield class invariants, that is, algebraic numbers in ring class fields of imaginary-quadratic number fields. We show that the singular values lie in subfields of the ring class fields of index 2 ′ −1 when k > 2 primes dividing the level are ramified in the imaginary...
متن کاملQuotients of Values of the Dedekind Eta Function
Inspired by Riemann’s work on certain quotients of the Dedekind Eta function, in this paper we investigate the value distribution of quotients of values of the Dedekind Eta function in the complex plane, using the form η(Ajz) η(Aj−1z) , where Aj−1 and Aj are matrices whose rows are the coordinates of consecutive visible lattice points in a dilation XΩ of a fixed region Ω in R, and z is a fixed ...
متن کاملDiscriminants and Ramified Primes
has some ei greater than 1. If every ei equals 1, we say p is unramified in K. Example 1.1. In Z[i], the only prime which ramifies is 2: (2) = (1 + i)2. Example 1.2. Let K = Q(α) where α is a root of f(X) = T 3 − 9T − 6. Then 6 = α3 − 9α = α(α− 3)(α+ 3). For m ∈ Z, α+m has minimal polynomial f(T −m) in Q[T ], so NK/Q(α+m) = −f(−m) = m3 − 9m+ 6 and the principal ideal (α−m) has norm N(α−m) = |m ...
متن کاملQuotients of Gaussian Primes
It has been observed many times, both in the Monthly and elsewhere, that the set of all quotients of prime numbers is dense in the positive real numbers. In this short note we answer the related question: “Is the set of all quotients of Gaussian primes dense in the complex plane?” Quotient sets {s/t : s, t ∈ S} corresponding to subsets S of the natural numbers have been intensely studied in the...
متن کاملEta-quotients and Elliptic Curves
In this paper we list all the weight 2 newforms f(τ) that are products and quotients of the Dedekind eta-function η(τ) := q ∞ Y n=1 (1− q), where q := e2πiτ . There are twelve such f(τ), and we give a model for the strong Weil curve E whose Hasse-Weil L−function is the Mellin transform for each of them. Five of the f(τ) have complex multiplication, and we give elementary formulae for their Four...
