Decoding of Projective Reed-Muller Codes by Dividing a Projective Space into Affine Spaces

, 2015
A projective Reed-Muller (PRM) code, obtained by modifying a (classical) Reed-Muller code with respect to a projective space, is a doubly extended Reed-Solomon code when the dimension of the related projective space is equal to 1.

On the Almost $\eta-$Ricci Solitons on Pseudosymmetric Lorentz Generalized Sasakian Space Forms

Universal Journal of Mathematics and Applications, 2023
In this paper, we consider Lorentz generalized Sasakian space forms admitting almost $\eta-$Ricci solitons in some curvature tensors. Ricci pseudosymmetry concepts of \ Lorentz generalized Sasakian space forms admitting $\eta-$Ricci soliton have ...

Fuzzy collineations of 3-dimensional fuzzy projective space from 4-dimensional fuzzy vector space

AIMS Mathematics
In this paper, the fuzzy counterparts of the collineations defined in classical projective spaces are defined in a 3-dimensional fuzzy projective space derived from a 4-dimensional fuzzy vector space. The properties of fuzzy projective space $ (\lambda, \

The projective space

Duke Mathematical Journal, 1950
The most striking feature of projective geometry is the principle of duality: If in a proposition about the projective space (the projective plane) we interchange points and planes (points and lines) we obtain a valid proposition. It thus seems natural to ask for a self-dual foundation of the theories in the sense that for every postulate the above ...

Generalized transversely projective structure on a transversely holomorphic foliation

International Journal of Mathematics and Mathematical Sciences, 2002
The results of Biswas (2000) are extended to the situation of transversely projective foliations. In particular, it is shown that a transversely holomorphic foliation defined using everywhere locally nondegenerate maps to a projective space ℂℙn, and ...

Directions and projective shapes

, 2005
This paper deals with projective shape analysis, which is a study of finite configurations of points modulo projective transformations. The topic has various applications in machine vision.

On the Projective Algebra of Randers Metrics of Constant Flag Curvature

Symmetry, Integrability and Geometry: Methods and Applications, 2011
The collection of all projective vector fields on a Finsler space (M,F) is a finite-dimensional Lie algebra with respect to the usual Lie bracket, called the projective algebra denoted by p(M,F) and is the Lie algebra of the projective group P(M,F).

A Simple Approach to Achieve Modified Projective Synchronization between Two Different Chaotic Systems

The Scientific World Journal, 2013
A new approach, the projective system approach, is proposed to realize modified projective synchronization between two different chaotic systems. By simple analysis of trajectories in the phase space, a projective system of the original chaotic systems ...

Quantization of symplectic tori in a real polarization

, 1996
We apply the geometric quantization method with real polarizations to the quantization of a symplectic torus. By quantizing with half-densities we canonically associate to the symplectic torus a projective Hilbert space and prove that the projective ...

N\'eron-Severi group of a general hypersurface

, 2016
In this paper we extend the well known theorem of Angelo Lopez concerning the Picard group of the general space projective surface containing a given smooth projective curve, to the intermediate N\'eron-Severi group of a general hypersurface in any ...
