On the structure of Hermitian codes1

Let X,,, denote the Hermitian curve xm+’ = ym + y over the field F,,,z. Let Q be the single point at infinity, and let D be the sum of the other rn3 points of X,,, rational over F,,,z, each with multiplicity 1. X,,, has a cyclic group of automorphisms of order m2 1, which induces automorphisms of each of the the one-point algebraic geometric Goppa codes &(D,uQ) and their duals. As a result, the...

Hermitian metric on quantum spheres

The paper deal with non-commutative geometry. The notion of quantumspheres was introduced by podles. Here we define the quantum hermitianmetric on the quantum spaces and find it for the quantum spheres.

On Modified Hermitian and Skew - Hermitian Splitting

the structure of lie derivations on c*-algebras

نشان می دهیم که هر اشتقاق لی روی یک c^*-جبر به شکل استاندارد است، یعنی می تواند به طور یکتا به مجموع یک اشتقاق لی و یک اثر مرکز مقدار تجزیه شود. کلمات کلیدی: اشتقاق، اشتقاق لی، c^*-جبر.

Convergence Properties of Hermitian and Skew Hermitian Splitting Methods

In this paper we consider the solutions of linear systems of saddle point problems‎. ‎By using the spectrum of a quadratic matrix polynomial‎, ‎we study the eigenvalues of the iterative matrix of the Hermitian and skew Hermitian splitting method‎.
