On the Representation of Numbers by the Direct Sums of Some Binary Quadratic Forms
The systems of bases are constructed for the spaces of cusp forms Sk(Γ0(3), χ) (k≥6), Sk(Γ0(7), χ) (k≥3) and Sk(Γ0(11), χ) (k ≥ 3). Formulas are obtained for the number of representation of a positive integer by the sum of k binary quadratic forms of the kind x1 +x1x2 +x 2 2 (6 ≤ k ≤ 17), of the kind x 2 1 +x1x2 +2x 2 2 (3 ≤ k ≤ 11) and of the kind x1 + x1x2 + 3x 2 1 (3 ≤ k ≤ 7). Let Fk denote ...
متن کاملOn Representation Numbers of Ternary Quadratic Forms
The representation number rQ(m) is the number of integral representations of the integer m by the integral quadratic form Q over a global number field. The main obstruction to obtaining information about representation numbers is that global integrally inequevalent forms might nevertheless be equivalent over every local field (i.e. in the same genus). This failure of the localglobal principle s...
متن کاملOn Representation of Integers by Binary Quadratic Forms
Given a negative D > −(logX)log2−δ , we give a new upper bound on the number of square free integers X which are represented by some but not all forms of the genus of a primitive positive definite binary quadratic form of discriminant D. We also give an analogous upper bound for square free integers of the form q+a X where q is prime and a ∈ Z is fixed. Combined with the 1/2-dimensional sieve o...
متن کاملEstimates for Representation Numbers of Quadratic Forms
Let f be a primitive positive integral binary quadratic form of discriminant −D, and let rf (n) be the number of representations of n by f up to automorphisms of f . In this article, we give estimates and asymptotics for the quantity ∑ n≤x rf (n) β for all β ≥ 0 and uniformly in D = o(x). As a consequence, we get more-precise estimates for the number of integers which can be written as the sum ...
متن کاملRepresentation of Prime Powers by Binary Quadratic Forms
In this article, we consider the representation of prime powers by binary quadratic forms of discriminant D = −2q1 . . . qt where the product of primes q1 . . . qt ≡ 3 (mod 4), for instance if it is of special RichaudDegert type n2 ± 2 for odd n’s, n2 − 1 for even n’s. We consider all the ambiguous classes and Q( √|D0|), where D0 is the fundamental discriminant and we obtain a general criterion...
