چکیده
In this paper we study the group K (n+1) 2n (F) where F is the function field of a complete, smooth, geometrically irreducible curve C over a number field, assuming the Beilinson–Soulé conjecture on weights. In particular, we compute the Beilinson regulator on a subgroup of K (n+1) 2n (F), using the complexes constructed in [dJ1]. We study the boundary map in the localization sequence for n = 3 (the case n = 2 was studied in [dJ2]). We combine our results with the results of Goncharov ([G1] and [G3], see also [G2]) in order to obtain a complete description of the image of the regulator map on K (3) 4 (C) and K (4) 6 (C), independent of any conjectures.

Fibre products of supersingular curves and the enumeration of irreducible polynomials with prescribed coefficients
For any positive integers n ≥ 3, r ≥ 1 we present formulae for the number of irreducible polynomials of degree n over the finite field F2r where the coefficients of xn−1, xn−2 and xn−3 are zero. Our proofs involve counting the number of points on certain algebraic curves over finite fields, a technique which arose from Fourier-analysing the known formulae for the F2 base field cases, reverse-en...
متن کاملComputing the rank of elliptic curves over real quadratic number fields of class number 1
In this paper we describe an algorithm for computing the rank of an elliptic curve defined over a real quadratic field of class number one. This algorithm extends the one originally described by Birch and Swinnerton-Dyer for curves over Q. Several examples are included.
متن کاملN ov 1 99 8 Neutrino Oscillations : a source of Goldstone fields and consequences for Supernovae ∗
It is shown that true Nambu-Goldstone (NG) bosons develop coherent fields whenever the associated charges of the matter particles are not conserved in a macroscopic scale. The sources of the NG fields are the time rates of quantum number violation. If the lepton numbers are spontaneously broken at a scale below 1 TeV, the neutrino oscillation processes generate classic NG fields that are strong...

We develop uniform approximations for the trace formula for non-integrable systems in which SU(2) symmetry is broken by a non-linear term of the Hamiltonian. As specific examples, we investigate Hénon-Heiles type potentials. Our formalism can also be applied to the breaking of SO(3) symmetry in a three-dimensional cavity with axially-symmetric quadrupole deformation. PACS number: 03.65.Sq
متن کاملOn isogeny classes of Edwards curves over finite fields
We count the number of isogeny classes of Edwards curves over finite fields, answering a question recently posed by Rezaeian and Shparlinski. We also show that each isogeny class contains a complete Edwards curve, and that an Edwards curve is isogenous to an original Edwards curve over IFq if and only if its group order is divisible by 8 if q ≡ −1 (mod 4), and 16 if q ≡ 1 (mod 4). Furthermore, ...
