Quantum codes from algebraic curves with automorphisms
Let X be an algebraic curve of genus g > 2 defined over a field Fq of characteristic p > 0. From X , under certain conditions, we can construct an algebraic geometry code C. If the code C is self-orthogonal under the symplectic product then we can construct a quantum code Q, called a QAG-code. In this paper we study the construction of such codes from curves with automorphisms and the relation ...
متن کاملAlgebraic curves over F2 with many rational points
A smooth, projective, absolutely irreducible curve of genus 19 over F2 admitting an infinite S-class field tower is presented. Here S is a set of four F2-rational points on the curve. This is shown to imply that A(2) = limsup#X(F2)/g(X) ≥ 4/(19 − 1) ≈ 0.222. Here the limit is taken over curves X over F2 of genus g(X)→∞.
متن کاملFixed points of automorphisms of real algebraic curves
We bound the number of fixed points of an automorphism of a real curve in terms of the genus and the number of connected components of the real part of the curve. Using this bound, we derive some consequences concerning the maximum order of an automorphism and the maximum order of an abelian group of automorphisms of a real curve. We also bound the full group of automorphisms of a real hyperell...
متن کاملOn the Geometry of Algebraic Curves Having Many Real Components
We show that there is a large class of nonspecial effective divisors of relatively small degree on real algebraic curves having many real components i.e. on M -curves. We apply to 1. complete linear systems onM -curves containing divisors with entirely real support, and 2. morphisms of M -curves into P.
متن کاملMany Generic Automorphisms
Given a theory T , one may add a new unary function symbol σ to the language and add axioms to T asserting that σ is an automorphism. The model theory of generic automorphisms is the study of the model companion of the resulting theory Tσ . In this paper, we study theories equipped with more than one generic automorphism by exploring when model companions exist for such theories. In particular,...
