Fp2-MAXIMAL CURVES WITH MANY AUTOMORPHISMS ARE GALOIS-COVERED BY THE HERMITIAN CURVE
Let F be the finite field of order q, q = p with p prime. It is commonly atribute to J.P. Serre the fact that any curve F-covered by the Hermitian curve Hq+1 : y = x + x is also F-maximal. Nevertheless, the converse is not true as the GiuliettiKorchmáros example shows provided that q > 8 and h ≡ 0 (mod 3). In this paper, we show that if an F-maximal curve X of genus g ≥ 2 where q = p is such th...
متن کاملOn Curves Covered by the Hermitian Curve
For each proper divisor d of (q − √q + 1), q being a square power of a prime, maximal curves Fq-covered by the Hermitian curve of genus 1 2 ( q− √ q+1 d − 1) are constructed.
متن کاملCaps on Hermitian varieties and maximal curves
A lower bound for the size of a complete cap of the polar space H(n, q2) associated to the non-degenerate Hermitian variety Un is given; this turns out to be sharp for even q when n = 3. Also, a family of caps of H(n, q2) is constructed from Fq2-maximal curves. Such caps are complete for q even, but not necessarily for q odd.
متن کاملGalois representations which are not minimally elliptic
In a recent preprint (see [C]), F. Calegari has shown that for l = 2, 3, 5 and 7 there exist 2-dimensional irreducible representations ρ of Gal(Q̄/Q) with values in Fl coming from the l-torsion points of an elliptic curve defined over Q, but not minimally, i.e., so that any elliptic curve giving rise to ρ has prime-to-l conductor greater than the (prime-to-l) conductor of ρ. In this brief note, ...
متن کاملCurves covered by the Hermitian curve
A family of maximal curves is investigated that are all quotients of the Hermitian curve. These curves provide examples of curves with the same genus, the same automorphism group and in some cases the same order sequence of the linear series associated to maximal curves, but that are not isomorphic. Dedicated with affection to Zhe-Xian Wan on the occasion of his 80-th birthday
